The correct answer is D) Black soil. The characteristics provided – richness in lime, iron, magnesia, and alumina; generally clayey, deep, and impermeable nature; and prominent presence in regions like Maharashtra, Madhya Pradesh, and Gujarat – are definitive features of Black soils (also known as Regur soils), which are largely derived from Deccan Trap lava rocks.
Black soil is characterized by its high clay content, moisture-retentive capacity, and common occurrence in the Deccan Plateau region of India, particularly Maharashtra, MP, Gujarat, and parts of Karnataka and Andhra Pradesh.
Black soil is highly suitable for growing cotton, hence also called ‘black cotton soil’. It develops deep cracks during the dry season, aiding in aeration, a phenomenon called ‘self- ploughing’.
