Which river is called the Sorrow of Bihar because of course shifting and floods?

Answer and explanation

Correct answer: Kosi

Option B is correct: the Kosi River is known as the Sorrow of Bihar. The governing concept is the behaviour of Himalayan rivers in their alluvial plains. The Kosi carries a large quantity of sediment from the young Himalayas and deposits it across the low-gradient plains. This deposition can raise the river bed and encourage the channel to shift, while intense monsoon rainfall increases the risk of flooding. Son, Ghaghara and Mahananda are also important rivers, but none is identified by this standard nickname in the question. The combination of frequent floods and changing course is the distinctive clue for Kosi. Therefore, option B correctly links the river with Bihar’s historical flood problem.
