Why should you list more than one font if you are formatting some text using CSS?

A. Not every browser supports every font
B. CSS will select the font that fits best on the page
C. CSS will use different fonts when the page is refreshed

A. Not every browser supports every font

By listing more than one font in the CSS, you can provide alternatives in case a specific font is not supported by a user's browser. This ensures that the text will still be displayed as intended, even if the user's browser does not support the first font listed.
