Correct Answer:
A. May and June
The correct answer is May and June. In Pakistan, the Kharif crop season typically commences with the onset of the monsoon rains, which usually occurs during the months of May and June. These are summer crops that require warm, wet conditions for growth.
- 'June and July' would be mid-season for sowing, not the start.
- 'April and May' is too early for the main Kharif sowing period, though some preparatory work might begin.
- 'None of these' is incorrect as May and June accurately mark the beginning of the Kharif period.
Understanding these agricultural cycles is crucial for crop planning and water management.
