Vulnerability to natural hazards in Meghalaya is often highest in:

Hilly areas with steep slopes
Coastal areas
Urban centers
Seismic fault zones

The correct answer is: a) Hilly areas with steep slopes.

Hilly areas with steep slopes are more vulnerable to natural hazards because they are more prone to landslides and flooding. Landslides can occur when the soil on a slope becomes saturated with water and loses its ability to support the weight of the overlying material. Flooding can occur when heavy rains or snowmelt cause rivers and streams to overflow their banks.

Coastal areas are also vulnerable to natural hazards, such as hurricanes, tsunamis, and sea level rise. Hurricanes can cause storm surge, which is a rise in sea level caused by the strong winds of the hurricane. Tsunami are large waves that can be caused by earthquakes, volcanic eruptions, or landslides. Sea level rise is the gradual increase in the average level of the world’s oceans.

Urban centers are also vulnerable to natural hazards, such as earthquakes, floods, and wildfires. Earthquakes can cause buildings to collapse and roads to buckle. Floods can cause damage to homes and businesses. Wildfires can destroy homes and businesses and can also cause injuries and deaths.

Seismic fault zones are areas where tectonic plates meet and can cause earthquakes. Earthquakes can cause damage to buildings and infrastructure, and can also cause injuries and deaths.

In conclusion, hilly areas with steep slopes are the most vulnerable to natural hazards in Meghalaya.
