• For the first option: The publication year is 2015 (from "2015" in the entry), and April 27, 2015 is the access date (from "Accessed 27 Apr. 2015"), so it was not published on that date.
• For the second option: The entry shows only one author (Witze, Alexandra), so it does not have more than one author.
• For the third option: The "Accessed 27 Apr. 2015" part of the Works Cited entry clearly indicates the work was accessed on April 27, 2015.
