Which option gives the correct comparative difference between Khadar and Bhangar?

Correct answer: Khadar is new fertile alluvium and Bhangar is old alluvium

Direct answer: Option A is correct. Khadar and Bhangar are both alluvial parts of the Northern Plains, but their age and flood relationship differ. Khadar is newer alluvium deposited on the active floodplain. Fresh sediment can be added to it during floods, and it is usually fertile. Bhangar is older alluvium found on a relatively higher terrace beyond the regular reach of floods; it may contain kankar. Option A states exactly this new-versus-old distinction. Option B is wrong because it reverses the descriptions: Khadar is not old kankar soil, and Bhangar is not the new flood soil. Option C is wrong because neither is a marine coral formation. Option D is wrong because neither is a mountain peak; both are depositional subdivisions of the plains. When answering, look first for the words “new,” “flood,” and “old.” New and flood-renewed means Khadar; old and often kankar-bearing means Bhangar. Memory cue: “Khadar comes again with floods; Bhangar belongs to the past.”
