Laterite has been derived from the Latin word ‘later’ which means brick. The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. Humus content of the soil is low because most of the micro organisms, particularly the decomposers, like bacteria, get destroyed due to high temperature. Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers. These soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Odisha and Assam. 

The Laterite Soil is the type of soil formed from intense leaching in areas of high rainfall , moisture and high temperature. The soil formed by the process of intense leaching is laterite soil.

Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated. 

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.
