The correct response is:
Sound waves are mechanical waves that can travel through a medium but cannot travel through a vacuum, while light waves are electromagnetic waves that can travel through a vacuum as well as through a medium.
However, it appears that this precise option is not presented in your list. The closest correct statement from the options provided would need to clarify that sound waves require a medium (solid, liquid, or gas) to propagate, whereas light waves do not require any medium and can travel through a vacuum.
