The smallest Richter magnitude that can be felt by a human varies depending on a person's location and sensitivity, but in general, a magnitude of 2.0 is considered the minimum threshold for detection. Magnitudes less than 2.0 can often only be detected by sensitive instruments. Therefore, both options A and B are too low, and Option D is too high.
