What are seismic waves? what is their relationship to earthquakes?

Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate theinterior of the Earth while surface waves do not.

When energy is released in the form seismic waves. the waves create movement forming an earthquake.

Ithink the answer is d.
