3. In summer, India experiences south-west monsoon winds, and in winter, north-east monsoon winds.

Complete solution step by step
What?
1. The word monsoon comes from the Arabic word mausim or the Malayan word monsin, meaning 'season.'
2. Monsoons are seasonal winds (Rhythmic wind movements) (Periodic winds) that with the change of season reverse their course.
3. The monsoon is a dual system of seasonal winds that flow during the summer from sea to land and during the winter from land to sea.
4. The Indian Monsoons are very large-scale convection cells.
5. They are normal or secondary winds that are seasonally reversed in the direction of the wind.
6. In summer, India experiences south-west monsoon winds, and in winter, north-east monsoon winds.
7. South-west monsoons are formed due to an intense low pressure system formed over the Tibetan plateau.
8. North-east monsoons over the Tibetan and Siberian plateaus are associated with high-pressure cells.

Factors affecting monsoon in India
1. Differential heating of Asia and the Indian Ocean landmass.
2. The presence of the Tibetan Plateau and the Himalayan ranges.
3. The presence of the upper air jet stream in the troposphere and its circulation.
4. Heavy-light snow occurred over the Tibetan Plateau.

C. Early June is the correct option.

Note
1. During the monsoon season, India receives about 70 percent of its annual rainfall, which also affects the yield of some primary Kharif or summer crops such as rice, pulses, and oilseeds such as soybeans.
2. A delayed monsoon can lead to problems with supply and even speed up food inflation.
3. In India, the Monsoon rains also replenish reservoirs and groundwater to help increase irrigation and also boost the output of hydropower.
