Which is the strongest clue to distinguish Bhangar from Khadar?

Answer and explanation

Correct answer: Old alluvium and presence of kankar

Direct answer: A is correct. Bhangar and Khadar are both alluvial parts of the Northern Plains, so their age is the strongest distinction. Bhangar is older alluvium deposited on higher terraces and is generally beyond the reach of ordinary annual floods. It may contain kankar, hard nodules commonly made of calcium carbonate. Therefore the clue “old alluvium plus kankar” identifies Bhangar. Option A is correct. Option B describes Khadar, the newer floodplain alluvium renewed by floods. Option C describes the pebbly Bhabar belt near the Shiwalik foothills, where streams disappear into porous deposits. Option D describes the marshy Terai south of Bhabar, where streams reappear and waterlogging is common. These are different zones, not the defining clue for Bhangar. Exam cue: old, elevated, kankar means Bhangar; new, low, flood-renewed means Khadar.
