Explanation:

The Red Panda is the state animal of Sikkim, an Indian state located in the Eastern Himalayas. This choice reflects the ecological significance of the Red Panda to the region, as Sikkim's forests provide a crucial habitat for this endangered species. Option A, West Bengal, has the Fishing Cat as its state animal. Option B, Kerala, has the Indian Elephant. Option D, Manipur, has the Sangai (Brow-antlered deer). Therefore, the Red Panda is uniquely associated with Sikkim as its state animal, highlighting conservation efforts.
