The correct answer is: The monsoon.
The monsoon is a seasonal wind pattern that occurs in many parts of the world, including India and Southeast Asia. It is caused by the difference in temperature between the land and the ocean. During the summer, 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, then flows in to fill this low pressure area. This flow of air is what causes the monsoon winds.
The monsoon winds bring with them a lot of moisture from the ocean. This moisture falls as rain when the air rises and cools. The amount of rainfall that a place receives depends on how close it is to the ocean and how strong the monsoon winds are.
Manipur is a state in northeastern India that is located close to the Bay of Bengal. This means that it is affected by the monsoon winds. The monsoon winds bring with them a lot of moisture from the Bay of Bengal, which falls as rain in Manipur. This is why Manipur experiences significant rainfall.
The other options are incorrect.
- Its proximity to the Bay of Bengal does not directly cause rainfall. The monsoon winds are what cause the rainfall.
- The Himalayan mountain range does not cause rainfall. The Himalayas actually block the monsoon winds from reaching some parts of India.
- Cyclonic activity is not a major cause of rainfall in Manipur.
