A Correct answer
Explanation

P-waves (primary waves) are compressional seismic waves that push and pull material in the direction of wave propagation. They're the fastest seismic waves and arrive first. S-waves shear material side-to-side, surface waves travel along Earth's surface, and 'interior waves' isn't a standard seismic category.
