The correct answer is b) Southwest Monsoon.
The Southwest Monsoon is a seasonal change in the direction of the prevailing winds in the Indian subcontinent. It blows from the southwest from June to September, bringing heavy rains to the western and southern parts of the country. The Southwest Monsoon is the main source of rainfall in Kerala, and the fishing season coincides with this time of year.
The Northeast Monsoon is a seasonal change in the direction of the prevailing winds in the Indian subcontinent. It blows from the northeast from October to December, bringing heavy rains to the eastern and northeastern parts of the country. The Northeast Monsoon is not as important for Kerala as the Southwest Monsoon, and the fishing season does not coincide with this time of year.
The Summer season is the warmest time of year in Kerala, and it runs from March to May. The weather is hot and humid, and there is little rainfall. The Summer season is not a good time for fishing in Kerala.
The Winter season is the coolest time of year in Kerala, and it runs from December to February. The weather is pleasant and there is moderate rainfall. The Winter season is a good time for fishing in Kerala.
