Explanation:

Anai Mudi, with an elevation of $2,695 \text{ m}$, is the highest peak in the Western Ghats and, consequently, the highest point in Peninsular India. Therefore, option B is correct. Option A, Shevroy Hills, are located in the Eastern Ghats and are significantly lower. Option C, Doda Betta, with an elevation of $2,637 \text{ m}$, is the highest peak in the Nilgiri Hills and the second highest in the Western Ghats, but not the overall highest in the peninsula. Option D, Mahendragiri, with an elevation of $1,501 \text{ m}$, is a prominent peak in the Eastern Ghats, but much lower than Anai Mudi. Thus, A, C, and D are incorrect.
