The correct answer is option 2 - Kharif. Kharif crops are sown soon after the onset of the South-West monsoon in India, which usually happens around June. These crops are dependent on rainfall for their growth and include crops like rice, maize, cotton, millets, and pulses. They are harvested in autumn or before the arrival of winter.

Option 1 - Rabi crops are sown in winter and harvested in spring. Option 3 - Rainfed refers to agricultural practices that rely on rainfall for irrigation, but it is not specific to the time of sowing. Option 4 - Dry farming refers to agricultural practices in areas with limited rainfall or water availability, but again, it is not specific to the time of sowing.

Therefore, Kharif is the appropriate term for crops sown soon after the onset of the South-West monsoon in India.
