How does the presence of glaciers in the Himadri range affect India's rivers?

Correct answer: It supplies perennial water to many Himalayan rivers

The direct answer is A. The Himadri, or Greater Himalaya, contains high snowfields and glaciers. Glaciers store snow and ice and release meltwater, especially during warmer seasons. This meltwater joins streams and helps many Himalayan rivers continue flowing through much of the year, so they are called perennial or relatively perennial rivers. Option A is correct because it describes the glacier-to-river water supply. Option B is wrong because glaciers do not make all rivers underground. Option C is wrong because rivers do not become coral islands; coral reefs are built by marine organisms in suitable warm, shallow seas. Option D is wrong because Himalayan rivers do not generally end in deserts merely because glaciers exist; many flow to the plains and seas. The statement says “many,” not every river, which makes it scientifically suitable. Memory cue: Himalayan glaciers act as natural water stores.
