Why do presenters use presentation aids? a. to make the presentation seem less credible b. to make the presentation more memorable c. to model the concepts of the presentation d. to ensure the presentation is entertaining

I'd probably go with B. It could be D, but I think you'd rather want a presentation to be memorable rather than just entertaining? I dunno.
