Answer:
b-Inability to make changes to slides
Explanation:
Slide Show mode allows you to see the presentation as the audience will view it and let you practise your speech. This mode helps you to see the final or current result of your presentation so that you can check if your work is satisfactory. It doesn't allow you to make changes to the slides, so if you want to make them, you have to exit from this mode, make changes and come back to slide show mode to see the corrections.
