The correct answer is Brahmaputra.

Key Points

• Brahmaputra
  • ​The Brahmaputra is a trans-boundary river that passes through Tibet, Bangladesh, and Northeastern India.
  • Other names for it include Luit in Assamese, the Yarlung Tsangpo in Tibetan, the Siang/Dihang River in Arunachali, and the Jamuna River in Bangla.
  • It is the 15th longest river in the world and the 9th largest by discharge.
  • The Yarlung Tsangpo River has its source in the Manasarovar Lake region, close to Mount Kailash, in Burang County, Tibet, on the northern face of the Himalayas.

Additional Information

• The river travels through southern Tibet before plunging into the Mountains in the Yarlung Tsangpo Great Canyon and entering Arunachal Pradesh.
• It enters India close to the Arunachal Pradesh settlement of Gelling and travels through Bangladesh as the Jamuna before flowing southwest through the Assam Valley (not to be confused with the Yamuna of India).
• It combines with the Ganges, also known as the Padma in Bangladesh, in the enormous Ganges Delta, where it then becomes the Meghna and eventually empties into the Bay of Bengal.
