Which Indian soil term is correctly associated with important geographical fact “it is more frequently flooded than the older alluvial terraces”, and also with “the newer alluvium of active floodplains”?

Correct Answer: Option D — Khadar. Khadar is correctly identified as it is more frequently flooded than the older alluvial terraces. Khadar is also associated with the newer alluvium of active floodplains. Another identifying fact about Khadar is that fresh silt renewal generally makes it highly fertile. A further exam-relevant fact about Khadar is that it is more frequently flooded than the older alluvial terraces. Why the other options are incorrect: • Option A — Bangar: Bangar is it is generally less frequently renewed by floods than khadar. It is incorrect here because Bangar is instead associated with the older alluvium of elevated river terraces. • Option B — Alluvial Soil: Alluvial Soil is it supports crops such as rice, wheat, sugarcane and jute. It is incorrect here because Alluvial Soil is instead associated with a transported soil deposited mainly by rivers. • Option C — Black Soil: Black Soil is its high moisture retention makes it especially suitable for cotton. It is incorrect here because Black Soil is instead associated with a clay-rich soil also called regur or black cotton soil. Exam Takeaway: Connect Khadar with “it is more frequently flooded than the older alluvial terraces” and “the newer alluvium of active floodplains” for revision.
