I would say A because the SETI Institute said, "Philip Morrison and Guiseppe Cocconi analyzed how two civilizations separated by many light years of space might use electromagnetic radiation to communicate.

Electromagnetic radiation is the general term for the more familiar light and radio waves."

So there you go!
