Answer : Option A
Explanation :
The longitudinal, transverse and surface waves in an earthquake originate from The focus within the body of the earth. The point where the energy is released is called the focus of an earthquake, alternatively, it is called the hypocentre. The energy waves travelling in different directions reach the surface. The point on the surface, nearest to the focus, is called epicentre. It is the first one to experience the waves. It is a point directly above the focus.
