The correct answer is: b) Kharif (monsoon)
Kharif is the most significant cropping season in Arunachal Pradesh. It is the main agricultural season in the state, and it accounts for the majority of the state’s agricultural production. The kharif season runs from June to September, and it is characterized by heavy rainfall. The main crops grown during the kharif season are rice, maize, millet, and pulses.
Rabi is the winter cropping season in Arunachal Pradesh. It is a shorter season than the kharif season, and it runs from October to March. The main crops grown during the rabi season are wheat, barley, and mustard.
Zaid is the summer cropping season in Arunachal Pradesh. It is a short season, and it runs from April to May. The main crops grown during the zaid season are vegetables, fruits, and spices.
All seasons are not equally important in Arunachal Pradesh. The kharif season is the most important season, followed by the rabi season and the zaid season.
