Which of the following is a kind of wave generated during an earthquake?

The P-wave, or primary wave, is a genuine type of seismic wave produced during an earthquake.

P-waves are the fastest seismic waves and are the first to reach a recording station.

There is no seismic wave called an N-wave in earthquake science.

There is likewise no O-wave among the recognised seismic waves.

A Q-wave is not a standard type of earthquake wave either.

The main seismic waves are P-waves, S-waves and the surface Love and Rayleigh waves.
