1. Barak

3. Subansiri

IASCODEX · Accepted Answer

Correct Option: B. 2 and 3 only

Strategy: Focus on the origins and courses of each river. Both Lohit and Subansiri originate and flow through Arunachal Pradesh, whereas the Barak primarily flows through Nagaland, Manipur, Mizoram, and into Assam, but not Arunachal Pradesh. Thus, only Lohit and Subansiri pass through Arunachal Pradesh.

Key Info: **Barak River**
Originates in the hills of Manipur, flows through Nagaland, Manipur, Mizoram, and Assam before entering Bangladesh as the Surma and Kushiyara rivers. It does not flow through Arunachal Pradesh.

**Lohit River**
Rises in eastern Tibet (Zayü district), enters India at Kibithu in Arunachal Pradesh, and travels extensively through the state before joining the Brahmaputra in Assam near Dibrugarh. It is a major river in eastern Arunachal Pradesh.

**Subansiri River**
The largest tributary of the Brahmaputra, it originates in the Tibet Autonomous Region, enters India through Arunachal Pradesh, and traverses the state before joining the Brahmaputra in Assam. Along with the Siang/Dihang, Dibang, and Lohit, Subansiri forms the major river system of Arunachal Pradesh. These rivers are critical to the state's hydrology, biodiversity, and serve as lifelines for the tribal communities.
