  1. A.Ayeyarwady River
  2. B.Sittaung River
  3. C.Chindwin River
  4. D.Wang Chhu River

Correct answer

D. Wang Chhu River

Explanation

The correct answer is D, Wang Chhu River. The Wang Chhu flows through western Bhutan and joins the Brahmaputra system in India.

The Wang Chhu rises in the Himalayas of Tibet, passes Thimphu and Paro in Bhutan, and enters West Bengal, where it is known as the Raidak. It then flows through Assam and meets the Brahmaputra. Several other Brahmaputra tributaries also come down from Bhutan, among them the Manas, the Sankosh and the Torsa, while the Subansiri, Dibang and Lohit join it in Arunachal Pradesh and Assam.

A is wrong: the Ayeyarwady, or Irrawaddy, is the main river of Myanmar and drains into the Andaman Sea. B is wrong: the Sittaung is also a river of Myanmar. C is wrong: the Chindwin is the largest tributary of the Ayeyarwady in Myanmar.

Exam tip: Brahmaputra tributaries from Bhutan - Wang Chhu (Raidak), Manas, Sankosh, Torsa; the Ayeyarwady, Sittaung and Chindwin belong to Myanmar.
