When you emphasize words in a quotation by underlining or italicizing them, you must note it by a. inserting a footnote. b. adding [sic]. c. adding (emphasis added). d. inserting an endnote.

C. adding (emphasis added)

Explanation:

This is how you should note the fact that you underlined or italicized words in a quotation. Adding emphasis to a quotation can be very useful. It allows us to bring attention to a particular phrase or word. However, it is important to note it so that the reader is aware of the fact that the emphasis is ours, and not from the original author.
