Which one of the following is not a tributary of the river Ganga?
- A.Son
- B.Mahananda
- C.Teesta
- D.Sharada
Correct answer
Explanation
The correct answer is C, Teesta. The Teesta rises in the glaciers of north Sikkim, flows through Sikkim and the Darjeeling hills into the plains of North Bengal, and then enters Bangladesh, where it joins the Brahmaputra (called the Jamuna there). It is therefore a tributary of the Brahmaputra system, not of the Ganga. Its waters are also the subject of a long-running water-sharing talk between India and Bangladesh. Option A is wrong because the Son, rising on the Amarkantak plateau, is a major right-bank tributary of the Ganga and joins it near Patna. Option B is wrong because the Mahananda, rising in the Darjeeling hills, is the easternmost left-bank tributary of the Ganga in West Bengal. Option D is wrong because the Sharada, also called the Kali along the India–Nepal border, joins the Ghaghara, which in turn flows into the Ganga. Exam tip: Teesta, Manas, Subansiri and Dibang go to the Brahmaputra; Son, Gomti, Ghaghara, Gandak, Kosi and Mahananda go to the Ganga.
