Correct option is C

A longitudinal wave is composed of both compression and rarefaction. 

Longitudinal waves are those in which the individual medium particles move in a direction that is parallel to the direction in which the disturbance is propagating. In the medium, the waves move through a succession of compressions and rarefactions.
