Which river in India has the highest volume of water flow?

It also has the highest silt content. Option A (“Ganga”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option B (“Godavari”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option D (“Mahanadi”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. The key concept is to match the water body with its basin, type, location and defining feature. Therefore the correct option, index and explanation consistently identify Brahmaputra. The Brahmaputra River has the highest volume of water flow (discharge) in India. It carries more water than any other river in India due to the heavy rainfall in its catchment area (Arunachal Pradesh and Assam receive some of the highest rainfall globally).
