Official UPSC Answer KeyUPSC Prelims 2010 • Geography

Correct Answer: Option (B) — Kolleru Lake : Krishna

Concept & Option Breakdown

Standard Reference Verified

• Option (b) is incorrectly matched: Kolleru Lake is a freshwater lake located between the Krishna and Godavari deltas in Andhra Pradesh, fed directly by the seasonal streams Budameru and Tammileru, not directly by the river Krishna. • Option (a) is correctly matched: Gobind Sagar is a reservoir on the Sutlej River formed by Bhakra Dam. • Option (c) is correctly matched: Ukai Dam (Vallabh Sagar) is constructed across the Tapi River. • Option (d) is correctly matched: Wular Lake in Jammu & Kashmir is fed by the Jhelum River.

Elimination Heuristic & Exam Approach

Kolleru is situated between the deltas of Krishna and Godavari and is directly fed by rivulets like Budameru, rather than the main channel of Krishna.
