The correct answer is: a) Kharif.
Kharif is the rainy season in India, which runs from June to September. It is the main growing season for rice, maize, and millets. These crops are planted in the monsoon rains and harvested in the late summer or early fall.
Rabi is the winter season in India, which runs from October to March. It is the main growing season for wheat, barley, and pulses. These crops are planted in the fall and harvested in the spring.
Zaid is the summer season in India, which runs from April to May. It is a short growing season for crops that can tolerate the heat, such as vegetables and fruits.
I hope this helps!
