The question relates to specific protected areas in India and the species they are famous for.

Option 1 states that Bhiterkanika in Orissa is well-known for Salt Water Crocodile. This is correct as Bhiterkanika National Park is known for its mangroves and the population of the Salt Water Crocodile.

Option 2 claims that the Desert National Park in Rajasthan is renowned for the Great Indian Bustard. This is also true since Desert National Park is one of the last refuges of Great Indian Bustard, a bird species that is critically endangered.

Option 3 says that Eravikulam in Kerala is famous for Hoolak Gibbon. This is incorrect because Eravikulam National Park is known for the Nilgiri Tahr, a type of mountain goat. The Hoolock Gibbons are found in the Northeastern states of India, not Kerala.

Hence, the correct answer is Option 2, i.e., 1 and 2 only, as they correctly match the protected areas to their famous species.
