Which of the following major rivers originates from the Chemayungdung glacier near Lake Mansarovar in Tibet, flows eastward across the Tibetan plateau, and enters India through Arunachal Pradesh under the name Siang?

💡 Solution & Explanation

The Brahmaputra River originates near Lake Mansarovar in Tibet, where it is known as the Yarlung Tsangpo. It flows eastwards across the Tibetan plateau before taking a dramatic hairpin bend around Namcha Barwa and entering India through Arunachal Pradesh, where it is called the Siang or Dihang. Upon receiving major tributaries like the Dibang and Lohit in the Assam valley, it becomes the mighty Brahmaputra. The Indus originates in a different sector near Tibet's northern slopes.
