If a question gives kankar, old alluvium and higher land as clues, what will be the answer?

Correct answer: Bhangar

The direct answer is B: Bhangar. In the Northern Plains, alluvium means sediment deposited by rivers. New alluvium, renewed frequently by floods, is called Khadar and is generally found in lower floodplain areas. Older alluvium, lying on slightly higher surfaces and often containing calcareous nodules called kankar, is called Bhangar. Therefore the clues can be matched step by step: kankar means older alluvium; older alluvium on higher ground means Bhangar. Option A, Terai, is the marshy, wet belt south of the Bhabar where underground streams reappear, so it does not fit. Option B is correct because it contains both identifying clues. Option C, Khadar, is newer floodplain alluvium and is renewed by floods, not the usual answer for old kankar-rich deposits. Option D, Bhabar, is a porous pebble belt along the Shiwalik foothills where streams disappear, not an old-alluvium plain. Exam cue: old and higher with kankar means Bhangar; new and flood-prone means Khadar.
