Answer 1

Hint: India possesses varied relief features, extreme climatic patterns, landforms, and vegetation types. All these results in the development of various types of soils in India. According to the Indian Council of Agricultural Research, the soil is classified into 8 varieties.

Complete Step by Step Answer: The 8 types of soil found in India are,
-Alluvial soil
-Red soil
-Black soil
-desert soil
-Laterite soil
-Saline soil
-Peaty/marshy soil
-Forest soil

The black covers about 15% of the total land area of India. It is mostly found in areas of Maharashtra, Gujarat, Madhya Pradesh and mostly in Deccan plateau areas.
-Black soils are mature soils which are deep and clayey. -They are rich in Iron, lime, calcium, potassium, aluminium and magnesium.
-They tend to become sticky when wet and shrink when dried. Therefore, they are impermeable. In dry seasons, they develop cracks.
-Black soil retains moisture for a longer period due to loss of moisture.
-Their colour varies from deep black to light black.
-Black soil is formed by the weathering of igneous rocks and solidification of molten lava.
-The death of living organisms contributes to the organic matter of the soil. This makes the black soil fertile.
Black soil is also known locally as regur soil due to its Indian origin.
Looking at the above options; the option a justifies the answer. The word "regular" is only known locally in India due to it's property to regurgitare which means to overflow.

Note: Black soil is good for production of cotton, wheat, jowar, Virginia tobacco, castor, sunflower and millets. Their iron-rich and granular structure makes them immune to wind and water.
