The correct answer is: B. South-West Monsoon
The South-West Monsoon is a seasonal wind that blows from the Indian Ocean to the Indian subcontinent between June and September. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean, causing the air to rise. This creates an area of low pressure over the land. The air from the ocean, which is cooler and at higher pressure, flows in to fill this low pressure area. This is the South-West Monsoon.
The South-West Monsoon is responsible for most of the rainfall in Chhattisgarh. The state receives an average of 1,000-1,500 mm of rainfall during the monsoon season. The rainfall is essential for the state’s agriculture and economy.
The other options are incorrect because they are not monsoon winds. The North-West Monsoon is a seasonal wind that blows from the North-West to the Indian subcontinent between April and June. The North-East Monsoon is a seasonal wind that blows from the North-East to the Indian subcontinent between October and December. The South-East Monsoon is a seasonal wind that blows from the South-East to the Indian subcontinent between December and February.
