What effect does monsoon have on India's river systems?

Correct answer: Monsoon can increase river flow

The direct answer is A: monsoon can increase river flow. Rain falling over river catchments, hills, and plains enters streams and rivers as surface runoff and through other forms of drainage. Therefore, during or after good monsoon rain, many rivers carry more water, although the exact effect differs by place and rainfall amount. A is correct. B is wrong because monsoon rain does not always dry rivers; it often replenishes them. C is wrong because rainfall and river flow are closely connected. D is impossible: rivers cannot be transformed into the Himalaya. Memory cue: more catchment rain generally means more river water, while deficient rain can reduce flow.
