The correct answer is C. Monsoon.
The monsoon is a seasonal reversal of wind direction between the northeast and southwest in the Indian subcontinent. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean in the summer, 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, flows in to fill this low pressure area. This is the monsoon wind.
The monsoon brings heavy rains to the Indian subcontinent. These rains are essential for agriculture and for the water supply of the region. However, the monsoon can also cause flooding, landslides, and other disasters.
The monsoon season in Telangana typically lasts from June to September. The heaviest rains usually occur in July and August. The monsoon is a vital part of the Telangana economy, but it also poses a significant risk to life and property.
