The statement is true for particles of the medium of an earthquake P-wave is:

They vibrate in a direction parallel to that of the wave, forming compression and rarefaction

P-waves can be produced by earthquakes and recorded by seismographs.

I am pretty sure that the only statement which is true for particles of the medium of an earthquake P-wave is being shown in the option : b) vibrate parallel to the wave, forming compressions and rarefactions. As you know, it can be formed in two ways : from alternating compressions and rarefactions or primary wave. I bet you will agree with me.
