    Incandencense is essentially what happens when a piece of metal gets so hot that it glows. Given that the only thing happening to the metal wire in the light bulb (in this case) is a change in temperature to cause it to shine, you should have enough information to answer your question.

    D and C are just meant to distract you. The real question you should be asking: "is change in temperature a chemical or physical change?"

    Thank you so much I think understand that now because chemical is something that you don't really do anything to it's the effect of something happening.
