Which of the following is not a Kharif crop?

The correct answer is Option (3) → Wheat

Indian crops are grouped by the season in which they are sown:

• Kharif crops — sown with the onset of the south-west monsoon (June-July) and harvested in September-October: paddy, bajra, jowar, maize, groundnut, cotton

• Rabi crops — sown in winter (October-December) and harvested in summer (April-June): wheat, barley, gram, peas, mustard

Wheat is a rabi crop: it needs a cool growing season.
