Electromagnetic radiation has no trouble at all traveling through vacuum.

We're very lucky that this is true. It means we can receive all the satellite TV we want to watch, and also, we can receive light and heat from the sun.

The answer is B because electromagnetic radiation does not need a medium to travel through.
