Electromagnetic radiation does not require a medium to travel through. Instead, it can exist in the form of photons in the absence of a medium.

Answer: The correct answer is Option B.

Explanation:

Electromagnetic waves are defined as the waves which have electrical and magnetic component associated with them. These waves are known as  transverse waves.

In these waves, particles of the medium travel perpendicular to the direction of the wave. These waves does not require any medium to travel through. They can travel through the vacuum.

Hence, the correct answer is Option B.
