Option (D) is correct. All of the above statements are true.
Further Explanation:
The sound waves produced by a sound source are the longitudinal waves. These waves are called as the longitudinal waves because the vibration of the particles in a longitudinal wave occurs parallel to the direction of propagation of the wave.
As the sound wave oscillates during their propagation, they create the areas of high pressure and low pressure. The areas of high pressure, where the waves are very close to each other and the density of the wave particles is comparatively higher than the other parts are termed as the compressions.
The areas of low pressure where the various waves are far away from each other and the density of the wave particles is comparatively lower than the other parts is termed as the rarefaction.
Therefore, the above explanations state that all of the above statements are correct.
