Correct Answer:
B. Jamuna
Explanation: The correct answer is Jamuna.
The Brahmaputra River originates in Tibet (as the Yarlung Tsangpo) and flows through India and Bangladesh. After entering Bangladesh, it splits into several distributaries. The main channel is known as the Jamuna River.
Key points about the Jamuna:
- It flows southward through central Bangladesh.
- It merges with the Ganges (Padma) near Goalundo Ghat.
- It is one of the largest rivers in Bangladesh by volume.
Why the other options are incorrect:
- Meghna: This river is formed by the confluence of the Padma and Jamuna, not a distributary of the Brahmaputra alone.
- Kaveri: This is a major river in southern India, completely unrelated to the Brahmaputra system.
- Narmada: This is a river in central India, flowing west into the Arabian Sea, not connected to the Brahmaputra.
Therefore, Jamuna is the correct answer.
