The choices can be found elsewhere and as follows:
A. ( Evan Burling, 7)
B. ( Burling 7)
C. ( The Social Security Wars, 7)
D. ( Burling, p.7)
I believe the correct answer from the choices listed above is option D. The correct parenthetical citation look for a quote or paraphrase from the source would be ( Burling, p.7). Hope this answers the question. Have a nice day.
