Exp) Option a is the correct answer.

Statement 1 is correct: The Jhelum, an important tributary of the Indus, rises from a spring at Verinag situated at the foot of the Pir Panjal in the south-eastern part of the valley of Kashmir. It flows through Srinagar and the Wular lake before entering Pakistan through a deep narrow gorge. It joins the Chenab near Jhang in Pakistan.

Statement 2 is incorrect: The Kolleru lake serves as a natural flood-balancing reservoir for two rivers. The lake is fed directly by water from the seasonal Budameru and Tammileru streams. It is connected to the Krishna (but not directly feeds) and Godavari systems by over 68 inflowing drains and channels.

Statement 3 is incorrect: Once a haven for migratory birds, the Kanwar lake in Bihar, Asia’s largest freshwater oxbow lake, is today a dying wetland ecosystem. It is a residual oxbow lake, formed due to meandering of Burhi Gandak river, a tributary of Ganga.
