Which argument is the best example of logos
a- Dad, everybody in school has this computer. I've got to have this computer. If I don't get this computer, I'll be depressed for a year.
b-Dad, you know what I'd love? A new computer. It would make me happy. Will you buy me a new computer?
c- Dad, because I know so much about computers, I can tell this is a good one, so I recommend we get it.
d- Dad, you should buy this computer for me because it comes with virus protection software and an extended warranty.
