When Delivering a Presentation, You Should

When delivering a presentation, you should:

A) fix your gaze on a point at the back of the audience, so it will appear as if you are looking at all of the attendees.
B) keep your eyes on your notes, so that you do not lose your place.
C) stare at each slide or at the board on which you have written points, so as to direct the audience's attention to it.
D) stare at the ground, so that you will not make eye contact with any of your audience members; this might distract your focus.
E) keep your eyes on your audience to pick up any visual clues from them.
