Answer:
The sentence that correctly uses an MLA in-text citation is the following one: According to fish biologist Sarah Myers, a single carp can spawn over a million babies (145). (D)
Step-by-step explanation:
In MLA style, you refer to the works of others by using what is known as parenthetical citation. That is, you should include all the relevant information regarding the source in parentheses. What is more, MLA format follows the author-page method of in-text citation: The author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and then a complete reference should appear on your Works Cited page. The name of the author might appear either in the sentence or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence.
