Which of the following is a Rabi crop?
Rabi crops are known as winter crops. They are grown in October or November. The crops are then harvested in spring. These crops require frequent irrigation because these are grown in dry areas. Wheat, gram, barley are some of the rabi crops grown in India. While rice, maize, bajra, jowar are a few of the Kharif crops grown in India. So these details show that Gram is Rabi crop and other ones are Kharif crop. Hence D is the correct option.
