Answer:
c. notes view
Step-by-step explanation:
Assuming you're talking about a slideshow program, like Microsoft PowerPoint, the notes view lets you see the speaker notes.
The normal view is the one used normally to present the regular slideshow content, it's formatted for a screen view.
The handout view is same as normal view, but formatted for print.
The slide sorter view is a general overview of your presentation allowing you to move your pages around.
