Source of Origin of Rivers in Tibet

The correct answer is option 'C' - Brahmaputra, Indus, and Sutlej.

Explanation:
Tibet, a region located in the Himalayas, is often referred to as the "Roof of the World" due to its high elevation. It is the source of several major rivers that flow through different countries in Asia. Let's explore each option and identify the rivers that have their source of origin in Tibet.

a) Brahmaputra, Ganges, and Sutlej:
- The Brahmaputra River originates in the Angsi Glacier, located in the southwestern part of Tibet.
- The Ganges River, on the other hand, does not originate in Tibet. It primarily flows through India and Bangladesh, with its source in the Gangotri Glacier in the Indian state of Uttarakhand.
- The Sutlej River also does not originate in Tibet. It originates from the Rakshastal Lake in the Tibetan Plateau but flows through the Indian states of Himachal Pradesh and Punjab.

b) Ganges, Sutlej, and Yamuna:
- As mentioned earlier, the Ganges and Sutlej rivers do not have their source of origin in Tibet.
- The Yamuna River also does not originate in Tibet. It originates from the Yamunotri Glacier in the Indian state of Uttarakhand, similar to the Ganges River.

c) Brahmaputra, Indus, and Sutlej:
- The Brahmaputra River originates in Tibet. It begins its journey near Mount Kailash and Lake Mansarovar in Western Tibet.
- The Indus River, one of the longest rivers in Asia, also originates in Tibet. Its source is near the Mansarovar Lake, close to Mount Kailash.
- The Sutlej River, as mentioned earlier, does not originate in Tibet.

d) Chenab, Ravi, and Sutlej:
- The Chenab River, Ravi River, and Sutlej River do not have their source of origin in Tibet. The Chenab River originates in India's Jammu and Kashmir region, while the Ravi River originates in the Indian state of Himachal Pradesh.

Therefore, the correct answer is option 'C' - Brahmaputra, Indus, and Sutlej. These three rivers have their source of origin in Tibet.
