The answer would be (C). Microwaves fall into the electromagnetic spectrum. What the electromagnetic spectrum shows us is all the forms of light that exists. The speed of light is the same as the speed of microwaves. The only things that differs within this spectrum is frequency and wavelength. In other words, all forms of electromagnetic radiation have the same speed.
Hope this helps.
