Which of the following is not a right hand tributary of River Brahmaputra ?

Question

Accepted Answer

Option 3 is the correct answer because the Kalong River is a left-bank tributary of the Brahmaputra River. It originates in the hills of Karbi Anglong district in Assam and joins the Brahmaputra from the south (left bank).

Here's why the other options are incorrect:

*   **Option 1 (Tista):** The Tista River is a right-bank tributary of the Brahmaputra (also known as the Jamuna in Bangladesh). It originates in the Himalayas and flows through Sikkim and West Bengal before joining the Brahmaputra.

*   **Option 2 (Manas):** The Manas River is a significant right-bank tributary of the Brahmaputra. It originates in the Himalayas in Bhutan and flows through Assam before joining the Brahmaputra.

*   **Option 4 (Subanseri):** The Subansiri River is the largest right-bank tributary of the Brahmaputra. It originates in the Tibetan Himalayas and flows through Arunachal Pradesh and Assam before joining the Brahmaputra.
