The correct answer is: A. Longitudinal waves.
Compressions and rarefactions are regions of high pressure and low pressure, respectively, that are created when a longitudinal wave travels through a medium. The particles in the medium move back and forth in the same direction as the wave is traveling.
Transverse waves, on the other hand, create regions of high and low pressure that are perpendicular to the direction of the wave’s travel. The particles in
