The sentence which uses proper MLA style for an in-text citation is "Taking a multivitamin daily does not reduce heart disease in men (Smith 22)." (option A)
<h3>How to structure an in-text citation?</h3>
When it comes to the MLA style, an in-text citation should mention the author's last name and the page number. The author's name may appear inside or outside parentheses, but the page number can only be inside.
With the information above in mind, we can safely select option A as the correct answer. Both the author's name, Smith, and the page number, 22, are inside parentheses.
