Answer:
The correct answer is d. Participants aggression.
Step-by-step explanation:
When there's a given situation in which an individual has to follow orders from an authority, the behaviors that she/he will elicit has little to do with his/her convictions and personal characteristics, and more with the social influence and self-justification that he/she poses on him/herself.
In this particular experiment, the participants were asked by a professor to administer electric shocks to the people that were being examined every time they answered the questions incorrectly. Because an authority figure was giving them orders they reluctantly comply with the requests.
In this particular case, they kept giving shocks to the subjects not because they were particularly aggressive, but rather because they wanted to comply with an authority figure.
In conclusion, the correct answer is d. Participants aggression.
