The correct answer is option C, Italy has experienced many earthquakes.
According to the theory of plate tectonics, Earth is an active planet. Its surface comprises various individual plates, which interact and move, continuously modifying and reshaping the outer layer of the Earth. Volcanoes and earthquakes both are the outcomes of the movement of tectonic plates.
Earthquakes take place on faults, strike-slip earthquakes take place on strike-slip faults, usual earthquakes take place on normal faults, and thrust earthquakes take place on reverse or thrust faults. When an earthquake takes place on one of these faults, the rock on one end of the fault slips in relation to the other.
