A
Correct answer
Explanation
Hirakud Dam, built across the Mahanadi River in Sambalpur district (1957), is the longest earthen dam in the world at approximately 26 km in length. It's also one of Asia's largest dams. The other options are dams in Odisha but none hold this world record. Kolab and Indravati are hydroelectric projects, while Chilika is a lake, not a dam.
