The correct option is (a).
Explanation
The Pachmarhi Biosphere Reserve is located in the Satpura Range of Madhya Pradesh. It consists of the Satpura National Park and the Bori and Pachmarhi Wildlife Sanctuaries. Endemic species are those found exclusively in a particular area and are not naturally found elsewhere. The fauna of this reserve represents a unique blend of species.
Statement-wise Analysis:
- 1. Bison (Indian Gaur) – Correct: The Bison is explicitly identified as an endemic fauna species of the Pachmarhi Biosphere Reserve.
- 2. Indian Giant Squirrel – Correct: The Indian Giant Squirrel (along with the Flying Squirrel) is a key endemic species found within the Pachmarhi Biosphere Reserve.
- 3. Snow Leopard – Incorrect: The Snow Leopard is an inhabitant of the high-altitude Himalayan ranges (alpine and sub-alpine zones). It is not found in the tropical deciduous forests of Central India.
- 4. Asiatic Lion – Incorrect: The Asiatic Lion is endemic to the Gir National Park and surrounding areas in Gujarat. It is not found in the Pachmarhi Biosphere Reserve.
Key Takeaway: The Pachmarhi Biosphere Reserve is known for specific endemic fauna such as the Bison and the Indian Giant Squirrel, distinct from the habitats of the Snow Leopard (Himalayas) and Asiatic Lion (Gujarat).
