Answer» Correct Answer - Option 3 : D
The correct answer is 12. - The rivers of India can be classified into four groups viz., Himalayan rivers, Deccan rivers, Coastal rivers, and Rivers of the inland drainage basin.
- The Himalayan Rivers are formed by melting snow and glaciers and therefore, continuously flow throughout the year.
- During the monsoon months, Himalayas receive very heavy rainfall and rivers swell, causing frequent floods.
- The Deccan Rivers on the other hand are rain-fed and therefore fluctuate in volume. Many of these are non-perennial.
- The Coastal streams, especially on the west coast are short in length and have limited catchment areas.
- Most of them are non-perennial. The streams of the inland drainage basin of western Rajasthan are few.
- Most of them are of an ephemeral character.
