Choose the correct answer from the given codes:
Answer: D
Notes:
Explanation: The Himalayan drainage system has evolved through a long geological history. It mainly includes the Ganga, the Indus and the Brahmaputra River basins.
- Since these are fed both by melting of snow and precipitation, rivers of this system are perennial.
- These rivers pass through giant gorges carved out by the erosional activity carried on simultaneously with the uplift of the Himalayas.
- Besides deep gorges, these rivers also form V-shaped valleys, rapids and waterfalls in their mountainous course.
- While entering the plains, they form depositional features like flat valleys, ox-bow lakes, flood plains, braided channels, and deltas near the river mouth.
