C Correct answer
Explanation

Sound waves are mechanical waves that require a material medium (solid, liquid, or gas) to propagate. They cannot travel through vacuum because there are no particles to compress and rarefy. Light and electromagnetic waves can travel through vacuum as they are self-propagating oscillating fields.
