A river formerly known as the ‘Sorrow of Bengal’ rises from Bihar is

Barakar
Damodar
Mayurakshi
Subamarekha

The correct answer is B. Damodar.

The Damodar is a river in eastern India. It rises in the Chhotanagpur Plateau in Jharkhand and flows through West Bengal, where it joins the Hooghly River. The Damodar is a major tributary of the Ganges River.

The Damodar was once known as the “Sorrow of Bengal” because of its frequent floods. In 1943, a major flood caused widespread damage and loss of life. In the 1950s, the Damodar Valley Corporation was established to control the river and prevent future floods.

The Damodar is a major source of irrigation and hydroelectric power. It is also a popular destination for fishing and boating.

The other options are incorrect because:

  • Barakar is a river in Jharkhand and West Bengal. It is a tributary of the Damodar River.
  • Mayurakshi is a river in Jharkhand and West Bengal. It is a tributary of the Bhagirathi River.
  • Subarnarekha is a river in Jharkhand and Odisha. It is a tributary of the Brahmani River.
