Answer 1

The correct option is D

(1), (2) and (3)

An Earthquake is a sudden tremor or movement of the earth's crust, which originates naturally at or below the surface. It includes shock waves caused by nuclear tests, manmade explosions and landslides caused by building work.
They can be linked to explosive volcanic eruptions; they are in fact very common in areas of volcanic activity where they either proceed or accompany eruptions.
​They can be triggered by Tectonic activity associated with plate margins and faults.
