I would say Food stamps. You can go with that or get a second opinion. Sorry if it's wrong.
I believe B would be the answer, as the subject closest to the verb (rolls) corresponds to the verb (when there is an "or" or "nor" in a sentence, the verb should correspond to the subject closest to it). For A, "adding machine" should correspond to "make," but it doesn't. For C, the subject is plural (team members and the coach), but the verb is singular; the case is the same for D.
