The question is asking us about the WORST option for a teenager who does NOT want to have sex?. Basically, if the teenager does not want to have sex, they should not do it against their will, so they should not cave into peer pressure - the correct answer is c. giving in to pressure. Ideally, they would be able to explain to the other person why, but if they can't, they can also just leave the situation (leave the room for example)
