The Peninsular region of India is known for its diverse wildlife, including Indian bisons (gaur), deer, and antelopes, which are commonly found in forests and grasslands of central and southern India.
- Indian Bison (Gaur) is found in the Western Ghats and central Indian forests.
- Deer and Antelopes are widely distributed in various parts of the peninsular region.
- Yak, however, is found in the Himalayan region at high altitudes and is not native to the Peninsular region of India.
Thus, the correct answer is Yak as it is not found in the Peninsular region.
