Answer:
B )Body language allows a presenter to interact with visuals and convey enthusiasm for the topic.
Explanation:
While body language does indeed allow a presenter to gesture with zeal to entertain and amuse the audience, it is not its role/purpose. Body language adds an element to compliment visuals such as a PowerPoint presentation by allowing the presenter to convey his or her mood and attitude for the content being presented. Having the audience be entertained would be secondary to the role of communicating the passion/enthusiasm for the material being presented.
