If you are in a situation where drinks are being served, your first decision should be a. to make sure everybody is having fun b. to call the police c. to call the parents d. to think of your personal safety

I believe the answer is D.  To think of your personal safety
Social situations that involves drink tend to be the most likely place where you make improper judgment/decisions because of Alcohol that impaired your decision-making process or another type of drugs that could be slipped into your drink without you knowing.
