RAS question
The Brahmaputra River enters India through which state?
Correct answer: (C) Arunachal Pradesh.
The Brahmaputra River enters India through Arunachal Pradesh, where it is known as the Dihang or Siang before flowing into Assam.
Explanation
The Brahmaputra is a trans-Himalayan river, so its correct state sequence matters more than only its best-known course in Assam. The river is known as Tsangpo in Tibet, enters India in Arunachal Pradesh as the Dihang or Siang, and then flows through Assam. India WRIS Wiki supports the same sequence: after flowing eastward parallel to the Himalayas, the river turns near Namcha Barwa, enters India in Arunachal Pradesh, is known there as Dihang, and then flows through Arunachal Pradesh and Assam. Therefore, the entry state is Arunachal Pradesh, not Assam.
Why the other options are wrong
- (A) Meghalaya is wrong because the Brahmaputra enters India in Arunachal Pradesh, not through Meghalaya.
- (B) Assam is wrong because the Brahmaputra flows through Assam after it has already entered India in Arunachal Pradesh.
- (D) Manipur is wrong because the Brahmaputra's Indian course does not pass through Manipur.
Concept
Indian drainage geography includes the state-wise course and local names of Himalayan river systems. RAS frequently uses river-entry points, transboundary names and Assam-Arunachal sequencing as map-based traps.
