Which one of the following protected areas is well-known for the conservation of a sub-species of the Indian swamp deer (Barasingha) that thrives well on hard ground and is exclusively graminivorous ?

Lists Kanha National Park (Madhya Pradesh) and indicates 'deer' and 'swamp-deer' among dominant species protected there.

A student could combine this with a map showing Kanha in central India and detailed range accounts of Barasingha to judge whether Kanha is a likely conservation site for that species/subspecies.

Identifies Barasingha (Swamp Deer) as occurring in 'Northern and Central India', giving a geographic range that overlaps with Madhya Pradesh where Kanha is located.

A student could use this range note plus Kanha's central-India location to infer plausibility that Kanha might conserve Barasingha or a subspecies.

Shows that particular national parks are noted for protecting specific endangered species/subspecies (e.g., Keibul Lamjao is tied to a named deer), establishing the pattern that parks often host and are associated with particular deer taxa.

A student could apply this pattern to ask whether Kanha similarly is associated in other sources with a named Barasingha subspecies and seek corroborating references.

Explains that national parks are strictly reserved for wildlife conservation and prohibit activities that harm habitats, implying parks can function as conservation strongholds for species/subspecies.

Using this rule, a student could reason that if Barasingha occurs in Kanha, the park's protection regime would support its conservation, so they should check species lists or management histories for Kanha.
