Research based on Bowlby's attachment theory indicates that the nature of a teenager's relationship with their parents significantly influences their social interactions with peers. Which of the following statements aligns with these findings? Question 5 options: Teens who frequently experience conflicts with their parents are likely to develop more dependent relationships with their peers, seeking the validation and support they lack at home.

Teens who have secure attachments to their parents often experience more distant relationships with peers, as they rely primarily on their family for emotional support. Teens who have more distance from their parents are likely to form closer friendships with peers due to their increased need for social connections.
