Agricultural crops in India are primarily classified into three seasons: Kharif, Rabi, and Zaid, based on the timing of their sowing and harvesting.
Step 1: Analyze the options.
(A) Winter: Rabi crops are known as winter crops. They are typically sown in mid-October to November and harvested in the spring (March–April).
(B) Summer: Zaid crops are grown during the short summer months between the Rabi and Kharif seasons.
(C) Monsoon: Kharif crops are sown at the beginning of the first rains in July, during the south-west monsoon season.
(D) None of these: This is incorrect as option (A) accurately identifies the season.
Step 2: Conclusion.
Since Rabi crops like wheat and peas require a cool climate for germination, they are sown in the Winter season.
