which category of waves best describes sound waves?\na surface waves\nb transverse waves\nc longitudinal…

Brief Explanations:

Sound waves are mechanical waves where the particles of the medium vibrate parallel to the direction of wave propagation. This is the characteristic of longitudinal waves. Surface waves occur at the interface between two media. Transverse waves have particle - vibration perpendicular to wave propagation. Electromagnetic waves do not require a medium and are different from sound waves.

Answer:

C. longitudinal waves
