The correct answer is: b) Cotton
Cotton is a major crop grown in the Rayalaseema region of Andhra Pradesh. The region is well-suited for cotton cultivation due to its warm climate and fertile soil. Cotton is a cash crop that provides a livelihood for many farmers in the region.
Rice is also a major crop grown in the Rayalaseema region. However, it is not as extensively grown as cotton. Rice is a staple food crop that is grown in many parts of India. The Rayalaseema region is not as well-suited for rice cultivation as other parts of the country, due to its drier climate.
Groundnut is another major crop grown in the Rayalaseema region. It is a legume that is used to produce oil and protein. Groundnut is grown in many parts of India, but it is not as extensively grown in the Rayalaseema region as cotton or rice.
Sugarcane is not a major crop grown in the Rayalaseema region. It is a tropical plant that is grown in many parts of India, but it is not well-suited to the climate of the Rayalaseema region.
