    A. It travels at the speed of light

    Explanation:

    Electromagnetic waves are the waves that are produced by an electromagnetic field carrying electromagnetic radiant energy. Electromagnetic waves travel at the speed of light.

    It can only be a transverse wave.

    It does not involve displacing a medium in the same direction the wave moves so it does not require a medium to travel through.
