Andrew Volunteered to Take Part in a Psychology Experiment to Earn

Andrew volunteered to take part in a psychology experiment to earn extra credit for his psychology class. The experiment was one that studied obedience, and Andrew was asked to deliver aversive (unpleasant) consequences to another student. Based upon what you know about the forces that influence a subject to continue obeying an experimenter's orders, which of the following reactions is most likely?

A) Andrew would refuse to take part in the experiment once he knew that he would have to deliver aversive consequences to another student.
B) Having volunteered to participate in the experiment for which he will receive extra credit, it is likely that Andrew will have the mental expectation that he should obey the experimenter.
C) Andrew would try to talk the experimenter out of delivering aversive consequences in favor of delivering pleasant consequences.
D) Andrew would not show up for the experiment on moral principles, because most people would believe that delivering aversive consequences to others is morally unacceptable under any circumstances.
