Which Indian soil term is correctly associated with source or location “deposited repeatedly along low-lying river floodplains”, and also with “fresh silt renewal generally makes it highly fertile”?

Correct Answer: Option B — Khadar. Khadar is correctly identified as deposited repeatedly along low-lying river floodplains. Khadar is also associated with fresh silt renewal generally makes it highly fertile. 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 located above the active floodplain in many northern plains. It is incorrect here because Bangar is instead associated with calcareous kankar nodules may occur within its profile. • Option C — Alluvial Soil: Alluvial Soil is widespread across the Indo-Gangetic-Brahmaputra plains and coastal deltas. It is incorrect here because Alluvial Soil is instead associated with it commonly contains varying proportions of sand, silt and clay. • Option D — Black Soil: Black Soil is extensive over the Deccan Trap region of Maharashtra, Madhya Pradesh and Gujarat. It is incorrect here because Black Soil is instead associated with it develops deep cracks during the dry season.
