You only have four choices. Which do you think doesn't belong?
my guess is displays but i'm really not sure.. the only one out of these the 10 questions i couldn't find
I'd vote for owners manual. Displays, advertising and charge accounts are designed to get people to spend money. An owners manual's purpose is to help the customer save money.
