The main difference between an incandescent bulb and a fluorescent bulb is that the incandescent bulb

A) heats a wire by sending an electric current through it, while the fluorescent heats a solid powdery material by sending a current through it.
B) uses electric current to heat a wire, while a fluorescent bulb sends an electric current through a gas.
C) uses electromagnetic radiation to heat a wire, while a fluorescent bulb uses magnetic fields to heat a gas.
D) heats a wire by sending an electric current through it, while a fluorescent bulb uses magnetic fields to heat a gas.
E) sends an electric current through a gas while the fluorescent bulb heats a thin wire electrically.
