The correct answer is option A

In a mechanical wave there is oscillation of the medium or matter. It is through the medium r matter that energy propagates. Sound waves require air for its propagation.

In Electromagnetic waves there are oscillation in the electric and magnetic fields which are perpendicular to each other and to the direction of propagation of the wave. Therefore, electromagnetic waves like radio waves can travel in vacuum.
