How does the Himalaya affect the origin of perennial rivers in India?
Answer and explanation
Correct answer: Himalayan snow and rainfall supply water to many rivers
The governing concept is the source and seasonal reliability of Himalayan river systems. High Himalayan glaciers and seasonal snowfall provide meltwater, while rainfall also feeds the rivers and their tributaries. Because these sources operate across different seasons, major rivers such as the Ganga, Yamuna, and Brahmaputra generally maintain flow for much of the year; hence option A is correct. The Himalaya does not stop all rivers, because many rivers originate there and pass through valleys. Its streams are not merely sandy, and the range contains abundant snow, ice, springs, and rainfall rather than having no water sources.
