Answer: A, "He should say "no" clearly and firmly state that he doesn't do drugs. If they pressure him, he should leave the scene."
Step-by-step explanation:
B is wrong. If they're too sensitive to understand no means no, they're sucky friends. You shouldn't want them as friends if they don't listen to what you want anyway. C is wrong ebcause you shouldn't have to do something, especially drugs, if you don;t want to , to be accepted into friend group. Hence, A is correct.
Although this is a schol question, do this in real life too, please. Nobody should ever pressure you into doing something you don't want to (drugs, drinking, sex, anything). It won't make you seem cool, look cool, and if it makes them like you more, they're just trash friends. If you want to do it, and responsibly, by all means, but do it responsily and most definitely, don't let your "friends" make that decision for you.
