Answer

Answer:

B. It is based on the size of seismic waves.

Brief Explanations:

The magnitude of an earthquake is determined by the amplitude (size) of the seismic waves recorded by seismographs. The Mercalli scale measures intensity, not magnitude. Magnitude is related to fault - movement, and while it can be related to damage, it doesn't directly determine damage.
