The correct answer is: a) Kharif.
Kharif is the main cropping season in Andhra Pradesh that coincides with the southwest monsoon. It is the rainy season in India, which runs from June to September. The monsoon rains are essential for the growth of crops, and Kharif crops are typically planted in the months of June and July. The main Kharif crops in Andhra Pradesh are rice, cotton, and maize.
Rabi is the second cropping season in India, which runs from October to March. It is the winter season, and crops are typically planted in the months of October and November. The main Rabi crops in Andhra Pradesh are wheat, barley, and pulses.
Zaid is a third cropping season in India, which runs from April to June. It is the summer season, and crops are typically planted in the months of April and May. The main Zaid crops in Andhra Pradesh are vegetables, fruits, and sugarcane.
Summer is not a cropping season in India. It is the hottest time of the year, and most crops cannot grow during this time.
