Answer: C) When the source goes into detail that you don't need.

When writing or giving a speech, we should paraphrase information instead of using a direct quote when the source we are using goes into detail that we don't need (if it is to extensive or specific), so in those cases, we can paraphrase the information, in order to emphasize in the subjects that we want to.
