The selected answer is wrong:
Sound wave can't travel in vacuum while light waves travel in a vacuum
REF: New School Physics
~waves /page 254-5
Absolutely correct, Sound wave is a mechanical wave that require material medium for propagation while light wave is a electromagnetic waves it does not require any material medium for propagation
There are some basic and fundamental properties peculiar to a light and sound wave that differentiates one from the other. These differences account for the ways light and sound waves have been studied and their principles applied in technological advancement in various industrial production processes, military warfare and entertainment. This post gives more insight and enlightenment on these fundamental differences between light waves and sound waves.

A wrong is wrong
the ans is B,sound waves requires material medium,bt light waves do not require material medium,it travels in free space.
bt sounds waves are both transverse and longitudinal.
