Answer

Brief Explanations:

P - waves are longitudinal waves. In longitudinal waves, particles of the medium vibrate parallel to the direction of wave - propagation and form compressions and rarefactions.

Answer:

B. They vibrate in a direction parallel to that of the wave, forming compressions and rarefactions.
