I tell the reader what the section is about. There might be several of these on one page. What text feature am I?
A:Title
B: Boldfaced print
C: Bullets
D: Captions
E: Headings
F: Subheadings
G: Color
H: Font
I: Size
J: Font Style
K: Italics
M: Labels

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.

Hope this helps, sorry if I'm wrong (cause I probably am!)
