The best response is:

c. Do not take a ride with someone who has been drinking. Call your parents and ask if you can stay a little later and if they can still pick you up.

It is never a good idea to get in the car with someone who has been drinking. You can get seriously hurt. It is important that you don't lie to your parents about how you will be getting home. The best thing that you can do is to call and speak with your parents honestly about the situation. Even if they do not want to pick you up later, it is important that you listen and respect their rules and get home safely.
