The correct answer is: a) Landslides.
Heavy rainfall during the monsoon season often triggers landslides in Meghalaya. This is because the soil in Meghalaya is very loose and unstable, and the heavy rains can cause it to erode and slide down the hills. Landslides can be very destructive, and they can often cause loss of life and property.
Droughts are periods of time when there is very little rainfall. This can cause problems for agriculture and other water-dependent industries. However, droughts are not typically associated with landslides.
Volcanic eruptions are caused by the release of magma from the Earth’s mantle. This can cause earthquakes, tsunamis, and other hazards. However, volcanic eruptions are not typically associated with landslides.
Tsunamis are large waves that are caused by earthquakes or volcanic eruptions. They can cause widespread damage and loss of life. However, tsunamis are not typically associated with landslides.
