Answer:

They vibrate the air.

Step-by-step explanation:

The sound waves in air are longitudinal while the light waves are transverse Sound wave is longitudinal because the medium particles move parallel to the direction of wave propagation, whereas a light wave is transverse because the medium particles move perpendicular to direction of wave propagation. Hence, option C is correct.
