Answer: The option that is correct is entry C. Stenger, Wallace, et al. Modern Composition. Holt, Rinehart and Winston, 1964.
Explanation: The MLA citation guide states that works-cited entries must start with the last name of the author of the text that is being cited. If the book/article was written by more than one person, the last and first names of the author that has been included must be followed by the expression "et al". The only entry in which "et al" is introduced is entry C. The MLA citation guide also states that this expression must be followed by the title of the text, the publishing company and the year of publication, as it has been included in entry C.
