Correct Option: B

The Alaknanda rises at the confluence and feet of the Satopanth and Bhagirath Kharak glaciers in Uttarakhand near the border with Tibet. The headwaters of the Bhagirathi are formed at Gaumukh, at the foot of the Gangotri glacier and Khatling glaciers in the Garhwal Himalaya. These two sacred rivers join to form the Ganges (Ganga) in Devprayag.
