Consider the following statements: 1. Silent Valley National Park is in the Nallamalai range. 2. Pathrakkadavu Hydroelectric project is proposed to be built near the Silent Valley National Park.

The correct answer is C because of the following reasons

Statement 1 is incorrect because Silent Valley National Park is located in the Nilgiri Hills of the Western Ghats in Kerala not in the Nallamalai range which is part of the Eastern Ghats in Andhra Pradesh and Telangana

Statement 2 is correct because the Pathrakkadavu Hydroelectric project was proposed on the Kunthipuzha river which flows through the Silent Valley National Park This project faced significant environmental opposition due to its proximity to the park
