Based on the given scenario above, I believe that the answer would be the third option: POSITIVE. The type of pressure that is being displayed in the given scenario above is positive peer pressure. Peer pressure can be identified into negative and positive. Negative when this influences someone to do things which would pose bad effects on you. On the other hand, positive peer pressure is the opposite as this influences you to be better. In this case, I can say that it is positive since this would develop the relationship and trust between you and your friend.
