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

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