Which one is newer alluvium among Bhangar and Khadar?

Khadar

Alluvium is material such as silt, sand, clay, and gravel deposited by rivers. In the Northern Plains, Bhangar and Khadar are two important divisions based mainly on the age and position of these deposits. Bhangar is the older alluvium, usually lying on slightly higher terraces. Khadar is the newer alluvium, deposited more recently in the low-lying floodplains and renewed by floods. This age difference is the key idea in the question.

Option A is correct because Khadar means the newer alluvial deposit. Bhangar is older, so option B gives the opposite relationship. A doab is the land between two rivers, not a category based on the age of alluvium. Terai is a wet belt near the Himalayan foothills, also not the name for newer alluvium. Therefore, when asked which is newer between Bhangar and Khadar, choose Khadar, option A.
