    GFCI is device that checks for ground leakage current and it is able to cut off power in case of detected leak.

    I don't want to help you with your homework but if your choices are taken loosely one of them is correct!

    I suppose the first thing is to be clear in your own mind as to what is a grounding fault. ie what happens during a grounding fault.

    That should enable you to immediately dismiss two of the options.

    Proper study of the code will allow you to answer the question, do either (or perhaps both) of the remaining two offer protection.

    Tell us what you think - note for the future - this part is a requirement for help on this site.

    Do you know where you might find each of the devices listed?

    A bit of a catch question, if they are applied in the right circumstance all can except the contactor.

    in the right circumstance contactor can be used to drop out circuit power.
    none of the mentioned devices offer ground fault protection but some of them can be used as part of the asked protection.
