Explanation:

- Doda Betta Peak is the highest mountain in the Nilgiri Hills, in Tamil Nadu.

- ? Option 2: The Nilgiri Hills is correct. Doda Betta Peak is located here.

- The Anaimalai Hills (Option 1) are a different range in the Western Ghats, also in Tamil Nadu and Kerala.

- The Vindhya Range (Option 3) is in central India, mostly in Madhya Pradesh. Doda Betta is not found here.

- The Satpura Range (Option 4) is also in central India, stretching through Madhya Pradesh, Maharashtra, and Chhattisgarh.

- So, out of the above, Doda Betta belongs to the Nilgiri Hills, not to the Vindhya, Anaimalai, or Satpura ranges.
