The correct option is C Brahmaputra
The Brahmaputra river has its origin in the Chemayungdung glacier of the Kailash range, near the Mansarovar lake. It traverses eastward longitudinally for a distance of nearly 1200 km in a dry and flat region of southern Tibet, where it is known as the Tsangpo. Tsangpo enters India after taking a U-turn at Namcha Barwa and flows into Arunachal Pradesh, where it is called Dihang river.
