Charlott finished the slides to use with her presentation. What question should she ask herself before the event to ensure the slides work well? A How many times should she practice in front of a mirror? How many people will be in the audience? C What hardware will she need when she presents? D What outfit will she wear for the presentation?

B. How many people will be in the audience?

This question is crucial for Charlott to consider because knowing the size of the audience will help her tailor the presentation to ensure the slides are visible and engaging for everyone. If the audience is too large, she may need to simplify the content or use larger fonts and images. Conversely, if the audience is small, she can afford to be more detailed and interactive.
