Answer 1

Hint: Dams are barriers that are formed to restrict the flow of water for various reasons like irrigation, flood control, navigability, aquaculture and production of electricity .

Complete answer: India has 5202 large dams. Nagarjuna Sagar is the tallest masonry dam in India.
Let us look at the options given to us-
Option (A ) Godavari is incorrect. Though Godavari basin has the largest number of dams, the Nagarjuna Sagar is not built over Godavari. Gangapur dam and Jayakpuri dams are dams built over Godavari.
Option (B ) Tungabhadra is incorrect as Tungabhadra, a tributary of Krishna , has Pampa Sagar dam on it.
Option (D ) Kaveri is incorrect as Kaveri has Krishna Raja Sagar dam, Mettur dam, Amravathi dam etc, but not Nagarjuna Sagar dam.
Option (C ) Krishna is correct as Nagarjuna Sagar dam is constructed over Krishna River. The construction started in 1956 and was completed by 1967. It is a masonry dam with a gross storage capacity of 11.472 billion cubic metres. It is one of the earliest multipurpose irrigation and hydroelectric projects in India and was built to achieve the goals of Green revolution.

Therefore the correct answer is option C.

Note: This dam is jointly operated by Andhra Pradesh and Telangana. The project also has the largest canal system network in India. Nagarjunakonda is a nearby hillock and island of Buddhist importance and the dam derives its name from this place.
