Where does the river Brahmaputra originate?

The correct answer is Option (2) → Lake Mansarovar

The Brahmaputra rises from the Chemayungdung glacier near Lake Mansarovar in southern Tibet, where it is called the Tsangpo. It flows east for about 1,200 km before turning south into India as the Siang or Dihang.

Namcha Barwa is the peak around which the river makes its great hairpin bend, not its source. Wular is a lake in the Jhelum’s course in Kashmir, and Verinag is the spring from which the Jhelum itself rises.
