Suicide is not something to joke about. Which is why if your friend is going through some tough times considering it. You should persuade them not to do it.
Suicide is serious, and no matter what they have done, they shouldn't think like that. Nobody is worthless. Always talk through it with them, and do whatever you have to in order to help. Talking to a suicide hotline, talking to trusted friends, adults, authority, even if you aren't the person friend, or if you don't know them, you should still help them. Your answer is B.
