It would be letter C - It's a numerical rating system that measures the largest seismic waves during an earthquake. 

The Richter scale is as a mathematical device to compare the size of earthquakes through a numerical rating system. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
