The correct answer is:
Entry D: Cottrell, Claire. "The Ruins of Champions: Photos of Abandoned Olympic Sites." The Atlantic, 14 Aug. 2012. www.theatlantic.com/entertainment/archive/2012/08/the-ruins-of-champions-photos-of-abandoned-olympic-sites/261114/.
because the name of the author is first and followed by a full stop and the title of the article is between quotes and followed by another full stop. Also, the title of the magazine is followed by the date and after the date there is a full stop and not a comma, like in entries A and B. Entry B is wrong also because the title of the article is not in quotes and answer C is wrong because the title of the article is followed by a comma and not a full stop and the title of the magazine is followed by a full stop and not a comma.
