The Correct Choice:  D

Longitudinal waves are a type of waves by which the medium is pushed only forward and backward not up and down. The best-known longitudinal wave is the Sound Wave.

Look at the pictures of athletes surfing. While ocean waves move forward they clearly pull the surface up and down. Look at the surface of the water in a pool. Surface waves might go in any direction but you clearly see the ups and downs. Transverse waves are completely the same. Actually they pull the particles of the media in a perpendicular direction to their propagation direction.

In contrast, longitudinal waves pull the particles in the same direction. Keep a string vertically, Stretch it and let it go. it will move in the same direction you pulled it. --> It's a Longitudinal Wave.
