Explanation
- A
Bandipur National Park-Karnataka
Bandipur National Park lies in Karnataka in the Nilgiri landscape and is part of the tiger reserve network. The State pairing is correct. This option is not the key.
- B
Manas Wildlife Sanctuary-Assam
Manas Wildlife Sanctuary, now also a national park and tiger reserve, is in Assam on the Bhutan foothills. The pairing is correct. This option is not the key.
- C
Periyar Wildlife Sanctuary-Kerala
Periyar Wildlife Sanctuary and tiger reserve is in Kerala around the Periyar lake in the Western Ghats. The pairing is correct. This option is not the key.
- D
Simlipal National Park-Madhya Pradesh
Simlipal National Park is in Mayurbhanj district of Odisha, not in Madhya Pradesh. The State name is wrong. This unmatched pair is the official key.
Summary. Official key is (d) Simlipal National Park–Madhya Pradesh. Bandipur is in Karnataka, Manas in Assam and Periyar in Kerala, so those three pairs are right. Simlipal is an Odisha tiger reserve in the Eastern Ghats of Mayurbhanj. Only (d) is incorrectly matched.
