What is the lower floodplain made of new alluvium called?

Answer and explanation

Correct answer: Khadar

Direct answer: Option C, Khadar. The Northern Plains have different alluvial surfaces. Khadar is the newer alluvium deposited by rivers, especially on the lower floodplain, and floods can add fresh layers of silt each year. Because the material is renewed, Khadar is generally more fertile. Option A, doab, means the land lying between two rivers; it is a location term, not specifically the name for new floodplain alluvium. Option B, Bhabar, is the pebbly belt along the Himalayan foothills where streams often disappear into porous deposits. Option D, Bhangar, is older alluvium, usually lying above the active floodplain and containing older deposits. Therefore the age and flood position are the deciding clues: new and regularly renewed = Khadar; old and higher = Bhangar. Memory cue: Khadar is “new,” while Bhangar is “old.”
