Answer:
E: Headings
Explanation:
Captions are describing a picture
Bullets are info
Boldfaced print, color, font size, font, and italics are all what the text looks like
Subheadings are describing different sections within a section
Labels are like captions
A title is what the whole entire thing is about. There is only one title
Headings tell you about the different subjects withing the whole topic, and there can be multiple of them.
Therefore, Headings would be correct.
