The correct answer is option 2, which correctly matches each National Park/Sanctuary with its location state.

A. Kanger Ghati National Park is indeed located in Chhattisgarh. This is why A matches with 1.

B. Nagerhole National Park is found in Karnataka, which corresponds with number 4, so B matches with 4.

C. Kugti Wildlife Sanctuary is located in Himachal Pradesh. This corresponds with 3, so C matches with 3.

Finally, D. Sultanpur Bird Sanctuary is located in Haryana, which corresponds with number 2.

Option 1, 3 and 4 have incorrect matches and hence those are not the correct answer. So, the correct mapping is indeed A-1, B-4, C-3, D-2.
