Statements A, B and C are correct. An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes occur at places where two tectonic plates interact. These can be convergent boundaries, divergent boundaries or transform faults (but, earthquakes largely occur along the converging plate boundaries as the energy released is higher). Epicentre is the point on the earth's surface vertically above the focus of an earthquake.
