Which of the following National Parks is unique in being a swamp with floating vegetation that supports a rich biodiversity?

States that Bhitarkanika along the coast of Odisha is the second largest mangrove of India (mangroves are a type of coastal swamp vegetation).

A student could note that mangrove ecosystems are typically swampy, often with floating or water-adapted vegetation, and check coastal maps or satellite images of Odisha to see Bhitarkanika's swampy mangrove environment.

Lists Bhitarkanika National Park as a Marine Protected Area, implying protection of intertidal/subtidal terrain and associated flora and fauna.

Use the MPA definition (intertidal/subtidal + associated flora/fauna) and basic coastal geography to infer Bhitarkanika includes wet, waterlogged habitats that support diverse species, then verify with maps or species lists.

Notes Bhitarkanika National Park and Sanctuary form an integral part of one Marine Protected Area, reinforcing its coastal/wetland character and conservation focus.

Combine this with standard knowledge that coastal MPAs commonly protect swampy mangrove areas and rich biodiversity; check regional habitat descriptions or imagery for floating vegetation presence.

Mentions that sanctuaries may be created for particular species and gives the example of a turtle sanctuary at Bhitarkanika, suggesting the area supports notable wildlife.

A student could infer that the habitat (likely wet/mangrove) sustains specialist fauna (e.g., turtles), and then consult species-habitat associations or maps to judge whether floating vegetation and swamp conditions are present.

Describes India's variety of wetland habitats and notes protected water‑fowl sites, establishing that India conserves wet, marshy systems which can harbour rich biodiversity.

Apply this general rule to Bhitarkanika (already identified as major mangrove/wetland) and use basic external resources (coastal location, Ramsar/MPA listings, imagery) to evaluate presence of swampy/floating vegetation and biodiversity.

Lists Keibul Lamjao among India's protected areas (national parks) alongside other wetland and habitat-protecting sites, implying it conserves a distinct habitat.

A student could check lists of protected wetland sites or Ramsar-designated areas and compare habitat descriptions to see if Keibul is classified as a swamp/wetland.

Describes Keibul Lamjao Wildlife Sanctuary as protecting species including water-birds and several deer, suggesting an aquatic or marshy habitat that supports diverse fauna.

Use basic geographic sources or satellite images to look for lakes/marshes at Keibul's location and confirm presence of water-bird habitats consistent with floating vegetation.

Names Keibul Lam Jao (Keibul Lamjao) with an endangered brown-antlered deer, indicating the park supports rare terrestrial fauna that often associate with specific wetland/grassland habitats.

A student could look up habitat requirements of the named endangered deer (e.g., dependence on marshy/meadow vegetation) to infer whether floating/swamp vegetation is likely present.

States India has a variety of wetland habitats and highlights protection of water‑fowl habitats (Chilika, Keoladeo), illustrating the pattern that protected sites are established where wetlands support rich biodiversity.

By analogy, a student can investigate whether Keibul Lamjao is similarly designated because it protects a wetland ecosystem rich in biodiversity.

Defines littoral and swamp forests and notes plant adaptations to water, providing a general pattern that swamp/littoral habitats support specialized vegetation and associated wildlife.

A student could compare the described plant adaptations and species composition with habitat descriptions or field images of Keibul Lamjao to judge if it fits a swamp with floating vegetation.

States Keoladeo National Park is protected as a water‑fowl habitat under the Ramsar Convention, linking the site to wetlands.

A student could use the Ramsar designation to infer wetland characteristics (e.g., marsh/swamp) and check maps or wetland descriptions to see if it has floating vegetation.

Notes the Siberian crane winters at Keoladeo and that this species breeds and winters in wetlands, tying the park to wetland habitats important for waterbirds.

Knowing cranes use marshy/wetland areas, a student could look up typical crane habitat (shallow marshes with aquatic vegetation) to assess if Keoladeo likely has such features.

Lists a wide range of water‑bird and other species protected at Keoladeo, indicating notable biodiversity associated with the site.

A student could compare the listed species (herons, teals, coots, etc.) with species that rely on swampy/floating vegetation habitats to evaluate compatibility.

Identifies Keoladeo‑Ghana National Park and notes an endangered wetland‑associated species (Siberian crane) as linked to the park, reinforcing its ecological importance.

Use the presence of such endangered wetland species as a cue to consult habitat descriptions or satellite imagery to check for marsh/swamp conditions and vegetation types.

Provides a general definition of littoral and swamp forests (plants adapted to breathing in water), offering a pattern of what swamp vegetation looks like.

A student could apply this pattern to ask whether Keoladeo's flora shows similar water‑adapted traits (or compare with photographic/satellite evidence) to judge if it is a swamp with floating vegetation.

States that India has a rich variety of wetland habitats and gives Keoladeo and Chilika as examples of protected water‑fowl wetland sites (Ramsar).

A student could use this pattern (national parks can be wetland/waterfowl habitats) plus a map or site description of Sultanpur to check if it is a wetland supporting waterbirds.

Defines the role of national parks as places where plant and animal species and habitats are preserved.

Combine this with local habitat data for Sultanpur to infer that if it is a wetland/swamp, it likely supports conserved biodiversity.

Mentions that ecosystems in the region include swamps and seasonally inundated areas as components of biodiversity hotspots.

Use this ecological pattern to reason that swamps/seasonally inundated wetlands typically harbour diverse species and could apply to Sultanpur if it is such a habitat.

Lists national parks (e.g., Dudhwa) protecting species associated with wetland or swamp habitats (swamp‑deer, hog‑deer, etc.).

This shows national parks with swamp species support rich biodiversity; a student could compare Sultanpur's species list to these to assess similarity.

Describes parks protecting wetland/marine/faunal communities (e.g., Manas has otter, swamp‑deer; Marine NP protects aquatic biota), illustrating that protected aquatic/swamp habitats sustain diverse life.

A student could use this rule to expect that if Sultanpur is an aquatic/swamp park it would similarly support diverse aquatic and bird species, then seek species records or maps to confirm.
