The Brahmaputra, Irrawady and Mekong rivers originate in Tibet and flow though narrow and parallel mountain ranges in their upper reaches. Of these rivers, Brahmaputra makes a “U” turn in its course to flow into India. This “U” turn is due to 

(a) Uplift of folded Himalayan series
(b) Syntaxial bending of geologically young Himalayas
(c) Geo-tectonic disturbance in the tertiary folded mountain chains
(d) Both (a) and (b) above

(b) Brahamputra originates near Mt. Kailash and is known to take a U turn near Mount Namcha Barwa. This U turn is also known as Great Bend. The U Turn is because of the 180° bend of the Himalayan structural trends.
