The correct answer is: d) Cotton.
Black cotton soils are deep, well-drained, and rich in organic matter. They are well-suited for growing cotton, which is a major crop in Andhra Pradesh. Cotton is a warm-season crop that requires full sun and well-drained soil. It is grown in a variety of soil types, but black cotton soils are ideal. These soils provide the nutrients and drainage that cotton needs to thrive.
Groundnut (a), rice (b), and jowar (c) are also important crops in Andhra Pradesh, but they are not as well-suited to black cotton soils as cotton. Groundnut is a legume that is grown in a variety of soil types, but it prefers well-drained, sandy loam soils. Rice is a water-intensive crop that is grown in flooded paddy fields. Jowar is a cereal crop that is grown in a variety of soil types, but it prefers well-drained, sandy loam soils.
In conclusion, cotton is the crop that is best suited for black cotton soils. These soils provide the nutrients and drainage that cotton needs to thrive.
