Answer: D is your correct answer
Explanation: The correct answer is D: According to fish biologist Sarah Myers, a single carp can spawn over a million babies (145).
Generally speaking, the correct MLA in-text citation for a book with one author is the author's last name and the page number (Myers 145).
However, because the author is named in the sentence, only the page number needs to appear in the citation. For that reason, answer D is correct.
