The correct answer is: a) Monsoon season.
The monsoon season is the rainy season in India, which typically runs from June to September. During this time, the southwest monsoon winds blow from the Indian Ocean towards the Indian subcontinent, bringing heavy rains. Tamil Nadu is one of the states in India that is most affected by flooding during the monsoon season.
The monsoon rains are essential for agriculture in India, but they can also cause widespread flooding and damage to infrastructure. In recent years, there have been several major floods in Tamil Nadu, causing extensive damage and loss of life.
The government of Tamil Nadu has taken steps to mitigate the risk of flooding, such as building dams and reservoirs to store excess water, and improving drainage systems. However, more needs to be done to protect the state from the devastating effects of flooding.
The other options are incorrect because:
- Summers are typically hot and dry in Tamil Nadu.
- Winters are mild and dry in Tamil Nadu.
- Post-harvest season is the time after the main harvest, when the land is left fallow. This is not a time when flooding is typically a problem.
