Solution

The correct option is B
Infrasonic

During the time of an earthquake, seismic waves are produced having a frequency in the range of $0.1 H z$ to $1 H z$ . Infrasonic waves are sound waves having a frequency less than the audible range, which is approximately $20 H z$ . Hence, sound waves produced due to an earthquake are infrasonic sound waves.
