I think I know what answer they are looking for, but I also don't think this particular GFCI is one that is required to be readily accessible.
Not going to give code section just yet because this may be homework question, but will suggest to OP to look into GFCI requirements in general for a start, as well as the mentioned 422 and how this particular appliance may be effected. I will talk about this further after some more time has passed or after someone does mention the article, quoting what it says will give too much away at this point, OP needs to learn to find this information if it is homework assignment.
