The correct answer is: (b) Tibet is cold and dry
Explanation:
The Brahmaputra River originates in the Tibetan Plateau near Lake Mansarovar and flows through Tibet before entering India and Bangladesh. While in Tibet, the river carries less silt and water due to the following reasons:
Cold and Dry Climate – Tibet has a cold desert climate with low rainfall, meaning there is less erosion and less water flowing into the river.
Limited Tributaries – In Tibet, the Brahmaputra does not receive many tributaries, so it remains shallow and slow-moving.
Glacial Source – The river is mainly fed by melting glaciers, which provide a steady but low volume of water in Tibet.
