Explanation:

In the context of soil types in India, Kankar refers to calcareous deposits, which are accumulations of calcium carbonate (CaCO₃) found in the soil. These deposits often appear as nodules or layers and are typically present in the Bhangar region, which consists of older alluvial soil. The presence of Kankar can affect soil fertility and water retention properties.

Other Options:

a) Bhangar: This is the term for the older alluvial soil found in the northern plains of India. It is characterized by the presence of Kankar deposits.

b) Khadar: This refers to the newer alluvial soil found in the floodplains of rivers. Unlike Bhangar, Khadar soil is more fertile and lacks the Kankar deposits.

c) Bhabar: This is a region located at the foothills of the Himalayas, characterized by porous and pebbly soil. It is not associated with calcareous deposits.

Therefore, the soil containing calcareous deposits is locally known as Kankar, which is found in the Bhangar region.
