Answer: C
Explanation: Both P‑ and S‑waves are seismic waves that are produced by (and produce the ground shaking of) earthquakes. They differ in particle motion: P‑waves are compressional (particles move parallel to the wave travel direction) while S‑waves are transverse (particles move perpendicular to the travel direction). Choices A, B and D are therefore not correct for both types.
