Option 1, which includes the rivers Brahmaputra, Indus, and Sutlej, is the correct answer. These rivers have their source of origin in Tibet. The Brahmaputra River originates in the Mansarovar Lake in Tibet, and then flows through India and Bangladesh. The Indus River also has its source in Tibet, specifically near Lake Mansarovar. It then flows through parts of India, Pakistan, and Afghanistan before reaching the Arabian Sea. The Sutlej River also originates in Tibet, from the Rakshastal Lake, and then flows through India and Pakistan. It is important to note that the other options listed do not have their sources in Tibet.
