The correct answer is: B. Damodar
The Tilaiya Dam is a concrete gravity dam on the Damodar River in Jharkhand, India. It was constructed between 1953 and 1963 for the purposes of irrigation, flood control, and hydroelectric power generation. The dam is 60 meters high and 670 meters long, and it has a reservoir capacity of 1.2 billion cubic meters. The Maithon Dam is also a concrete gravity dam on the Damodar River, located downstream of the Tilaiya Dam. It was constructed between 1957 and 1962 for the same purposes as the Tilaiya Dam. The Maithon Dam is 78 meters high and 770 meters long, and it has a reservoir capacity of 2.7 billion cubic meters.
The other options are incorrect. The Barakar River is a tributary of the Damodar River, and the Subarnarekha River and the Mayurakshi River are both tributaries of the Ganges River.
