Consider the following statements: How many of the statements given above are correct?

Answer: (a) Only one

Only the Wular statement is correct.

Statement by statement

1. ✓ CORRECT The Jhelum flows into and out of Wular Lake.

2. ✗ WRONG Kolleru is fed by the Budameru and Tammileru streams and linked by channels; the Krishna does not feed it directly.

3. ✗ WRONG Kanwar Lake (Kabartal, Begusarai) was formed by the meandering of the BURHI Gandak, not the Gandak.

The idea

A water body can be a through-flow lake, a stream-fed depression or a cut-off river bend. These origins require different river links. Check direct drainage rather than regional proximity, and treat Gandak and Burhi Gandak as distinct names.

Meander grows across the floodplain → Bend neck narrows → High water cuts across the neck → Main channel takes the shortcut → Sediment closes the old entrances → An oxbow wetland is left behind

Why the others are wrong

(b) Accepts the Krishna or the Gandak link.

(c) Two statements are wrong.

(d) The Jhelum–Wular link is correct.

The trap

Gandak vs Burhi Gandak — one word changes the river.

Elimination technique

Jhelum–Wular guarantees at least one correct statement, excluding (d). Burhi Gandak rather than Gandak excludes (c); checking Kolleru’s local feeders resolves (a) against (b).

Loktak’s phumdis are floating vegetation mats, not abandoned river bends. Chilika and Pulicat have coastal barriers and sea connections. Dal and Wular share the Kashmir setting but have different forms and drainage details. Lake origin is a useful second memory link after location.
