Answer: Option B
Solution:
The epicentre of an earthquake is the nearest point to the surface from the focus perpendicular to the earth's surface. It generally lies within a depth of 6 kms in the earth crust. The point vertically above the focus on the earth's surface is called as the epicenter. The intensity of earthquake will be highest in the epicenter and decreases as one moves away.
