Department store manager: There is absolutely no reason to offer our customers free gift wrapping again this holiday season. If most customers take the offer, it will be expensive and time-consuming for us. On the other hand, if only a few customers want it, there is no advantage in offering it. Which one of the following is an assumption required by the department store manager's argument?
A: It would be expensive to inform customers about the free gift wrapping service.
B: Gift wrapping would cost the store more during this holiday season than in previous holiday seasons.
C: Either few customers would want free gift wrapping or most customers would want it.
D: Anything that slows down shoppers during the holiday season costs the store money.
Choose A, B, C or D as your solution.
