The correct answer is c) Cyclones and coastal hazards.
Nagapattinam and Cuddalore are districts in the Indian state of Tamil Nadu. They are located on the east coast of India, and are therefore highly vulnerable to cyclones and coastal hazards. Cyclones are severe tropical storms that form over warm waters in the tropics. They can cause widespread damage to coastal areas, including flooding, wind damage, and storm surge. Coastal hazards include erosion, flooding, and sea level rise. These hazards can also cause significant damage to coastal areas.
Droughts are periods of time with below-average rainfall. They can cause crop failures, water shortages, and wildfires. Earthquakes are sudden movements of the Earth’s crust. They can cause buildings to collapse, roads to crack, and bridges to fall. Forest fires are uncontrolled fires that spread through forests. They can cause damage to trees, wildlife, and property.
In conclusion, Nagapattinam and Cuddalore are highly vulnerable to cyclones and coastal hazards. These hazards can cause significant damage to coastal areas, including flooding, wind damage, and storm surge.
