Which element of a business document provides additional information but is not a part of the body of the text?

a. subject

b. footer

c. salutation

d. closing note

The subject is generally covered inside the body of text, so that one's out.

The footer is a completely separate part of the document, specifically the bottom-most portion of the page, but let's look at the others.

The salutation is placed at the beginning of the body of text.

And your closing note is placed at the end of the body of text.

So, the best answer would be b. footer.
