Wich of the following sttatement about private club guests is correct?

This is a weird question, but I think its D. B is out, how do guests own beverages the club is serving? They're guests! C is wrong because the club wants to make bucks, its private, so they will try to make as much money as possible. And A is out because why will they pay for the service of the Alcoholic Beverage. Unless they served it on gold plates, they wont charge for the service. So D has to be the answer. Hope I helped!
