The correct answer is option 2, i.e. 2 and 3 only Himalayan rivers originate from the lofty mountains but peninsular rivers originate in the peninsular plateau. Himalayan rivers have larger basins and catchment area than peninsular regions. Himalayan rivers are perennial in nature i.e. water flows throughout the year in these rivers while the peninsular rivers receive water only from rainfall and water flows in these rivers in rainy season only. Therefore, they are seasonal in nature. Hence statement 2 is correct. Himalayan rivers flow across the young fold mountain and still in a youthful stage while peninsular rivers have been flowing in one of the oldest plateau of the world and have reached maturity. Hence statement 1 is not correct. After entering the plains Himalayan rivers form meanders and shift their beds because of a sudden reduction in speed of flow of water. While in the case of a peninsular river, hard rocks of the plateau have little scope for meandering activities. Hence statement 3 is correct.
