Explanation: When writing citations for a classic play, we have to be careful to follow the correct format. According to MLA format, we have to write in parentheses, the name of the play (or the abbreviation) without quotation marks, and then write the numbers of the act, scene and lines that we are referring to, they must be in the mentioned order, and separated by periods. So the option D is the correct one and it refers to Macbeth, act 4, scene 2, lines from 7 to 15.
