RAS question
The Brahmaputra River is known by which name in Bangladesh?
Correct answer: (D) Jamuna.
In Bangladesh, the Brahmaputra River is known as the Jamuna.
Explanation
The Brahmaputra changes names along its course: Tsangpo in Tibet, Dihang or Siang in Arunachal Pradesh, Brahmaputra in Assam, and Jamuna in Bangladesh. The cited World Bank blog directly confirms the Bangladesh usage, noting that barges on the Indo-Bangladesh Protocol route enter Bangladesh's section of the Brahmaputra and that, in Bangladesh, the Brahmaputra River is known as the Jamuna. This matters because the river system is often tested through its regional names and confluences: in Bangladesh, the Jamuna joins the Padma, the name used for the Ganges there, and then the Meghna before reaching the Bay of Bengal through the Ganga-Brahmaputra-Meghna delta.
Why the other options are wrong
- (A) Meghna is not the Bangladesh name of the Brahmaputra; it is a separate river named in the downstream sequence after the Jamuna-Padma confluence.
- (B) Surma is a different river in Bangladesh, so choosing it confuses another Bangladeshi river name with the Brahmaputra's Bangladesh name.
- (C) Padma is the name used for the Ganges in Bangladesh, not for the Brahmaputra.
Concept
This tests river nomenclature across political and physiographic regions, a recurring RAS theme in Indian geography. The Brahmaputra is especially important because exam questions often link its regional names with Bangladesh's river confluence pattern.
