Why is Khadar understood in relation to flood plains?

Answer and explanation

Correct answer: Because it is formed by new alluvium repeatedly deposited by rivers

Khadar is the newer alluvium found in low-lying flood-plain areas. During floods, rivers spread fresh layers of fine sediment over nearby land. Because this material is deposited repeatedly, Khadar is generally renewed more often than older alluvial surfaces. Its connection with flood plains comes from this active process of river deposition. The term therefore describes a river-made plain, not a mountain, coral island, or lava plateau.

Option A gives the correct reason: Khadar forms from new alluvium repeatedly deposited by rivers. Option B refers to a Himalayan peak, option C describes a coral island, and option D describes a hard volcanic landform. None of those processes explains Khadar. The key contrast is between newer Khadar and older alluvium called Bangar. Hence option A is the correct choice.
