Which is an example of peer pressure based on a reasoning tactic?

This does have options, right? If so:
A.) All my friends in the 10th grade are doing it. You should do it too or you won't be our friend.
She reasoned that if everyone is doing it, then it's fine. 
I hope this helped :) 

Her parents start noticing changes about her. she's probably just competive though not on drugs

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
