Which one of the following rivers is also known by the name of "Dihang" in Northeast India ?

  1. A.Dikhow
  2. B.Brahmaputra
  3. C.Subansiri
  4. D.Teesta

Correct answer

B. Brahmaputra

Explanation

The correct answer is B, Brahmaputra. In Arunachal Pradesh the Brahmaputra is called the Dihang, or Siang, the name it carries after it enters India from Tibet. The river rises in the Chemayungdung glacier of the Kailash range near Lake Mansarovar and flows east across southern Tibet as the Yarlung Tsangpo. Near Namcha Barwa it makes a sharp U-turn through a deep gorge and enters India in Arunachal Pradesh as the Siang or Dihang. In Assam, after the Dibang and the Lohit join it near Sadiya, it becomes the Brahmaputra, and in Bangladesh it is called the Jamuna. Option A is wrong because the Dikhow is a small south-bank tributary of the Brahmaputra in Assam, flowing down from Nagaland. Option C is wrong because the Subansiri is a separate north-bank tributary that joins the Brahmaputra in Assam. Option D is wrong because the Teesta rises in Sikkim and flows through West Bengal into Bangladesh. Exam tip: Tsangpo in Tibet, Siang or Dihang in Arunachal, Brahmaputra in Assam, Jamuna in Bangladesh.
