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. 3. The Kunthi river originates in Silent Valley’s rainforests. Which of the statements is/are correct?

Statement 1 is incorrect: Silent Valley National Park lies in the Nilgiri Hills of Palakkad district in the Western Ghats, not the Nallamalai (Eastern Ghats) range [1]. Statement 2 is supported in the sources: a hydroelectric project affecting Silent Valley was proposed (and later stopped) as part of plans to dam the Kunthipuzha basin, indicating that a hydel scheme was indeed planned near the park [2]. Statement 3 is correct: the Kunthi (Kunthipuzha) River flows through the valley and emerges from rainforests in the Silent Valley area before joining the Bharathapuzha [3]. Therefore, only statements 2 and 3 are correct.
