Deception in Psychology Experiments

Deception in psychology experiments:

A) has not been allowed since the 1960s when participants in Stanley Milgram's obedience study were not told beforehand that they would have to use electric shock to punish the "learner" every time the "learner" made a mistake.
B) is still allowed when it is not feasible to use alternatives that do not involve deception, and when the potential findings justify its use because of the scientific, educational, or applied value.
C) is expressly forbidden by the provisions in the 2002 APA ethical guidelines and regulations.
D) is allowed under the 2002 APA ethical guidelines without any restrictions or conditions.
