Black soil is mainly found in Maharashtra, Saurashtra, Malwa, Madhya Pradesh, Karnataka and Chhattisgarh. They are well known for their capacity to hold moisture and are rich in soil nutrients.
Hence, option $C$ is the correct answer.

This type of soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows. 

These soils are black in colour and are also known as regur soils. They cover the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh and extend in the south-east direction along the Godavari and the Krishna valleys.

The organic fertilizers are used to improve the fertility of alluvial soil. This type of fertilizer originates from an organic source. Some examples include fish extracts, manure, and compost. 

The black soil is also known as Regur soil. Black soil is ideal for growing cotton. 

The black soils are made up of extremely fine i.e. clayey material. They are well-known for their capacity to hold moisture. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents. 

This is the most widely spread and important type of soil. In fact, the entire Northern Plains are made of alluvial soil. The alluvial soil consists of various proportions of sand, silt and clay. Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime.

Orchards can very well be grown in mountainous soil. These soils are heterogeneous in nature and their character changes with parent rocks, ground-configuration and climate. Consequently, they differ greatly even if they occur in close proximity to one another.

The soil is soft during wet and very hard during dry is Black Soil.
