The correct answer is: B) The monsoon.
The Kharif cropping season in Madhya Pradesh coincides with the monsoon season, which is from June to September. The monsoon is a period of heavy rainfall that occurs in India and other parts of South Asia. The monsoon is important for agriculture in Madhya Pradesh, as it provides the water that is needed to grow crops.
The other options are incorrect. Summer is the hottest season of the year in Madhya Pradesh, and it is not a good time to grow crops. Winter is the coldest season of the year in Madhya Pradesh, and it is also not a good time to grow crops. Spring is a good time to grow crops in Madhya Pradesh, but it does not coincide with the monsoon season.
