i) The rainfall is a product of the convergence of the Bay of Bengal wind flow and the South China Sea reverse winds.
ii) The monsoon is based on the relief characteristics of the winds carrying the soil and the direction of the rain.
iii) The average annual rainfall in our country is around 120 cm, most of which falls over four months, and during this time the entire country receives almost 75% of its rainfall.

Complete answer:
Monsoon refers to the full reversal of winds over a wide region leading to a change of seasons. Break refers to the monsoon's rainy and dry spells. The monsoon rains, in other words, take place for a few days at a time. Rainless cycles are interspersed with them.

Southwestern monsoons are winds that provide India with maximum rainfall. Due to high pressure produced in the Indian Ocean, these winds carry rain towards the end of the summer. In the month of June, the monsoon reaches the Malabar Coast and leaves the country by November. Much of India's food production relies on the monsoons.

The following are the options given:
A) The winter season is brought to India by the north-east monsoon. Option A is therefore an incorrect choice.
B) South-west monsoons are the winds that provide India with maximum rainfall. Option B is therefore the right answer.
C) During the months of October and November, the disappearance of south-western monsoon winds from the skies of northern India is known as the withdrawing monsoon. Option C is therefore not the correct answer.
D) The trade winds are winds that blow east-west just north and south of the equator consistently. The winds help ships navigate west, and storms such as hurricanes can also be steered as well. Hence, Choice D is also not the correct response.

Hence the correct answer is option ‘B’.

Note: It is the monsoon winds from the south-west that carry heavy rainfall to Cherapunji. The local winds are known as mango showers, which carry light rainfall to India and are beneficial for coffee and tea plants. As it lies on the eastern side of the Western Ghats, Tamil Nadu is regarded as a rain shadow region.
