What type of wave is sound? longitudinal surface light transverse

Hi Animal! 

Your answer is A. longitudinal

In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion. A sound wave traveling through air is an example of a longitudinal wave.
