Which deposits can generally be found in Bhangar?

Correct answer: Kankar deposits

Direct answer: Option A is correct. Bhangar is the older alluvial terrace of the Northern Plains. Since it is old, its deposits have had time to develop nodules or concentrations of calcium carbonate called kankar. These kankar deposits are a standard identifying feature of Bhangar. Option A works because it connects old alluvium with kankar. Option B is wrong because coral rocks form mainly through marine organisms in warm shallow seas, not as the normal deposit of Bhangar. Option C is wrong because “sea salt mountains” are not a recognised characteristic of this inland alluvial surface. Option D is wrong because lava islands are volcanic features formed by erupted magma, whereas Bhangar is formed by river sediments. A useful comparison is that Khadar is newer, lower and regularly renewed by floods, while Bhangar is older, relatively higher and may contain kankar. Do not treat every plain deposit as the same: age and material matter. Memory cue: “Bhangar is old, so kankar can be told.”
