Correct Answer: Eastern and Southern part of the Deccan Plateau

Solution : The correct answer is the Eastern and Southern parts of the Deccan Plateau.

Red soil is made up of an alluvium red layer, a thin layer of highly organic and organic-mineral soil and a lot of clay. This type of soil typically results from crystalline and metamorphic rock weathering in locations with considerable rainfall. It is found mainly in low rainfall areas of the Deccan plateau, and some parts of Odisha, the foothills of Western Ghats, Chhattisgarh, and the Southern plains of Ganga.
