Solution
The correct option is C Black soil
Explanation:
The parent material for most of the black soil are the volcanic rocks that were formed in the Deccan Plateau (Deccan and the Rajmahal trap). The black soil is highly retentive of moisture. It swells greatly on accumulating moisture. Strenuous effort is required to work on such soil in the rainy season as it gets very sticky. In summer, the moisture evaporates, the soil shrinks and is seamed with broad and deep cracks. The lower layers can still retain moisture. The cracks permit oxygenation of the soil to sufficient depths and the soil has extraordinary fertility. Thus self-ploughing is a characteristic of the black soil.
