Correct Option (b)
Kolleru Lake is a natural freshwater lake situated between the deltas of the Godavari and Krishna rivers in Andhra Pradesh. It is primarily fed by seasonal streams such as Budameru and Tammileru, and not directly by the main Krishna River. The lake functions as a flood-balancing reservoir. Therefore, the pairing of Kolleru Lake with the Krishna River is not correctly matched.
