Which of the following shows the correct parenthetical citation for a quote from page 91 of an article in the october 2002 issue of travel america magazine called “backroads of oklahoma,” written by mary r. simpson?
a) (simpson 91)
b) (“backroads” 91)
c) (travel america 91)
d) (“backroads of oklahoma,” 91)

One of the rules in proper parenthetical citation says that when the author of the source is given, it should be written using the author's name and page number. But if without the author's name, the title of the book or article is used as a subsitute, following the page number. Since the name of the author has been mentioned, the correct answer would be, letter A. (Simpson 91)
