The correct answer is: A. Khadar
Khadar is the newer alluvium, while bhangar is the older alluvium. Khadar is deposited by the rivers during the monsoon season, while bhangar is deposited by the rivers during the non-monsoon season. Khadar is usually fertile and is used for agriculture, while bhangar is usually infertile and is used for grazing.
Khadar is a type of alluvium that is deposited by rivers during the monsoon season. It is usually found in the floodplains of rivers and is composed of fine-grained sediments, such as silt and clay. Khadar is often fertile and is used for agriculture.
Bhangar is a type of alluvium that is deposited by rivers during the non-monsoon season. It is usually found on the banks of rivers and is composed of coarse-grained sediments, such as sand and gravel. Bhangar is often infertile and is used for grazing.
