The origin and mechanism of South-West Monosoon is NOT associated with______________.

Correct option is C

The South-West Monsoon in India is primarily influenced by factors like the differential heating of land and sea, upper air circulations, and ENSO (El Niño-Southern Oscillation). However, western disturbances, which are extratropical storms originating in the Mediterranean region, affect the weather in North and Northwestern India during winter and have little to do with the South-West Monsoon. 
Information Booster:
· South-West Monsoon: It is caused by differential heating of the Indian subcontinent and surrounding oceans, creating pressure gradients that draw in moist winds from the Indian Ocean.
· ENSO: The El Niño-Southern Oscillation is a climate pattern that affects the strength of the monsoon. El Niño typically weakens the monsoon, while La Niña strengthens it.
