I got this question in unit test.

This interesting question is from Indian Rivers and Their Classification topic in portion Rivers Behaviour, Control and Training of Irrigation Engineering

Answer 1

Correct option is (d) 50 to 100

The best I can explain: Since the Himalayan Rivers are perennial rivers, there is a risk of a rise in high floods during rainy seasons. This leads to flood discharge as great as 50 to 100 times the normal winter flow. The surface runoffs are also unpredictable.
