Answer:
The appropriate way to complete an in-text citation would be option 3:
"Even notorious journalists are not fans of The Great Gatsby. One journalist states, "I find Gatsby aesthetically overrated, psychologically vacant, and morally complacent" (Schulz, 2013)."
This format includes the author's last name and the year of publication within parentheses after the quote. It is important to give credit to the source of the quote in a clear and consistent way, so the reader can easily find the source in the reference list.
