Show answer & explanation
Correct answer: D
India's climate is divided into four meteorological seasons: Winter (December-February), Summer (March-May), the South-West Monsoon or rainy season (June-September), and the Retreating Monsoon, also called Autumn or the post-monsoon season (October-November). Each season is identified by whether the monsoon winds are yet to arrive, are advancing onto the land, or are withdrawing back towards the sea.
Statement A is false: "south-west monsoon season" is the name of the summer rainy season (June-September); Autumn is instead called the Retreating Monsoon or the north-east monsoon season.
Statement B is false: in Autumn, the monsoon winds weaken and withdraw, blowing from the land back towards the Bay of Bengal and the Arabian Sea - the reverse of what the statement describes.
Statement C is false: the "onset and advance" of the monsoon is what marks the South-West monsoon season in June; Autumn is instead marked by the monsoon's withdrawal.
Each of A, B, and C is in fact a defining feature of the South-West monsoon season, not of Autumn: the name in A, the onshore wind flow in B, and the onset/advance in C all belong to the June-September rainy season. Autumn (October-November) is the season that follows it, when the winds reverse and retreat towards the sea.
So all three statements are false when applied to Autumn, and the correct choice is the option stating A, B, and C are all false.
