Answer 1

Answer: (A), (B), (D)

The correct options are
A It covers around 46% of total land area.
B It contains adequate proportion of potash, phosphoric acid, and lime.
D It is found along river valleys, in floodplains, and deltas.

The Himalayan river systems deposited large amounts of soil in the Northern Plains over a large period of time. This soil is found extensively in the Northern Plains and other river valleys in India. This soil, which is very fertile, is called alluvial soil and is well suited for agriculture. It is also found in the eastern coastal plains, especially in the deltas of the Mahanadi, Godavari, Krishna, and Kaveri rivers.
