The MLA format requires that for in-text citation you use C. Author-page method.
The MLA format always uses the author- page method, meaning that the author’s last name and the page number from which the quote or paraphrase is taken should be included in the text. The author’s name can appear in the sentence or in parentheses at the end of the quotation together with the page number. The complete reference should be written in the Work Cited page.
