Which pair correctly matches region and wildlife?

Correct answer: Kaziranga and one-horned rhinoceros

The direct answer is B: Kaziranga and the one-horned rhinoceros. To match a region with wildlife, recall the animal most strongly associated with that protected area. Kaziranga National Park is in Assam and is internationally known for the Indian one-horned rhinoceros, which lives in its grasslands and wetlands. The chain is: Assam location, Kaziranga habitat, rhinoceros conservation; therefore B is correct. A is wrong because the Sundarbans are mangrove wetlands famous for the Bengal tiger and other mangrove wildlife, not camels. C is wrong because Gir is associated with the Asiatic lion, whereas yak are adapted to high cold mountains. D is wrong because the Thar is a hot desert suited to desert animals such as camels; it is not the standard regional match for crocodiles. Therefore B is the only accurate pair. Exam memory: “Kaziranga–Assam–one-horned rhinoceros” is a useful three-part link.
