If a river deposits new fine sediments every year, that area belongs to which category?

Correct answer: Khadar

The direct answer is A, Khadar. Alluvium is sediment such as fine silt, sand, and clay carried and deposited by a river. In the Northern Plains, newer alluvium is called Khadar. It is usually found in the lower floodplain and may receive fresh sediment when the river overflows each year. Step by step: the river carries particles; flooding slows the water; the particles settle; repeated yearly deposition makes the surface young and renewed. Option A is correct because Khadar means new alluvial soil, commonly renewed by floods. Option B, Bhangar, is older alluvium lying above the active floodplain; it is not freshly deposited every year and may contain kankar nodules. Option C, Bhabar, is a narrow belt near the Shiwalik foothills where coarse pebbles are deposited and streams often disappear underground. Option D, a plateau, is an elevated, relatively level landform, not a flood-deposited plain. Memory cue: Khadar is “new” alluvium; Bhangar is “old” alluvium.
