Answer:
C) reviewing her speaking outline for points that could use visual support.
Explanation:
When using a slide for a presentation, only the important points should be highlighted in the slide. Some concepts are more difficult to understand and Letitia would benefit her audience more if she highlighted difficult concepts and made it easier for her audience to understand using visual support.
So when preparing her speech, Letitia should review her outline for points that need visual support to aid understanding.
