Answer:
The correct answer is C. Both are first-person accounts of the plague, but Defoe's is historical fiction while Pepys' diary is a nonfiction, primary source document.
Explanation:
Maybe the reason why Defoe's account of the events were so fictitious were because the time it occurred, he was just about 5 years old, hence he might not have been able to remember everything. Probably most of his information he took from books, newspapers and sermons about the plague. However Pepy used the primary source because he was older and was at the very heart of it when it happend. He even some times used personal pronouns to refer to himself in the document.
