• C. Regur
• D. None of these

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The alluvial soils of the North Indian plains are classified based on their age. The question asks for the name of the older alluvium.

Step 2: Detailed Explanation:
\[\begin{array}{rl} \bullet & \text{Bhangar: This refers to the old alluvial soil. It is found in the higher terraces of the floodplains, away from the river banks. It is less fertile than Khadar and often contains calcareous concretions known as 'kankars'.} \\ \bullet & \text{Khadar: This refers to the new alluvial soil. It is found in the low-lying areas of the floodplains near the river. It is replenished by fresh deposits of silt every year during floods, making it extremely fertile.} \\ \bullet & \text{Regur: This is another name for black soil, which is found primarily in the Deccan Plateau and is ideal for growing cotton.} \\ \end{array}\]

Step 3: Final Answer:
The old alluvial soil of the Ganga plain is called Bhangar.
