Answer
Correct option: A.
Longitudinal
Longitudinal waves, also known as $l-$waves, are waves in which the displacement of the medium is in the same direction as the direction of travel of the wave. Longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium. In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave.
