Explanation:

The correct option is (B) June - July. Kharif crops, also known as monsoon crops, are sown at the onset of the southwest monsoon season in India, which typically occurs during the months of June and July, when sufficient rainfall is available for germination and initial growth. Option (A) April - May is generally too early for the main Kharif sowing. Options (C) November - December and (D) October - November correspond to the sowing and early growth periods for Rabi crops (winter crops) or the harvesting period for Kharif crops, respectively, not their sowing season.
