B
Correct answer
Explanation
The term epicenter specifically refers to the point on Earth's surface directly above the origin (focus) of an earthquake. The prefix 'epi-' means 'on' or 'above', so epicenter is the surface point above the earthquake's underground starting point. It is not related to nuclear explosions, cyclonic storms, or other phenomena in this context.
