Correct Answer: Due to the southwest monsoon

Solution : The correct option is Due to the southwest monsoon .

Most parts of India experience rainfall from June to September due to the influence of the southwest monsoon, which is a seasonal wind pattern. During the summer months, there is a temperature difference between the landmass of India and the Indian Ocean. The landmass heats up more quickly than the ocean, creating a low-pressure area over the land. Meanwhile, the Indian Ocean retains its relatively cooler temperature, resulting in a high-pressure area over the ocean.
