Solution

The correct option is A Volcanic rocks

Typically found in lava-covered areas, soils are generally referred to as "black cotton soils." The term black cotton soil is coined because in the region where the black soil is found, cotton is the typical crop. Black soil is created by the weathering of lava (a igneous rock) and the cooling of lava after a volcanic eruption. Rich in humus, iron and also high quality magnesia, lime and alumina.

The correct answer is A .
