Show answer
Answer: B. Statement 1 is correct: parts of the western coast were submerged after tectonic movements, linked with the Peninsular Block. Statement 2 is correct: the Peninsula has old, worn-down residual hills such as the Veliconda and Mahendragiri. Statement 3 is wrong: deep V-shaped valleys of fast young rivers belong to the Himalaya; Peninsular rivers have broad, shallow valleys. So 1 and 2.
Watch for: Students forget that the old, stable Peninsula has mature rivers, not young gorge-cutting ones.
Why the other options are wrong
- A. Wrong because statement 2 is also correct.
- C. Wrong because V-shaped gorges are a Himalayan feature.
- D. Wrong because statement 3 describes the Himalaya, not the Peninsula.
