Consider the following statements : 1. River Kaveri has well developed valley 2. Valley of River Alakananda is still growing 3. River Krishna is largest east flow¬ing peninsular river Which of the statements given above is/are correct ?

Statement 1 is correct as the Peninsular drainage system, including the Kaveri, is older than the Himalayan system, characterized by broad, largely-graded shallow valleys and rivers in a mature stage [2]. Statement 2 is correct because Himalayan rivers like the Alaknanda are much younger and still actively engaged in significant vertical and lateral erosion, forming deep gorges and rapids as their valleys continue to grow [2]. Statement 3 is incorrect; while the Krishna is a major east-flowing peninsular river, the Godavari is the largest among them [2]. The Godavari has the largest basin area in the Peninsula, whereas the Krishna is the second largest [3]. Therefore, only statements 1 and 2 are accurate regarding the geomorphological maturity of the Kaveri and the youthful, growing nature of the Alaknanda valley.
