Final answer:
Answer: Peer pressure. Adolescents often conform to the behaviors, norms, and attitudes of their peers, a social phenomenon known as peer pressure. This is part of their socialization and aids in developing independence and a sense of identity.
Step-by-step explanation:
The process by which adolescents choose to participate in shared norms, roles, and expectations within a group dynamic is most commonly referred to as peer pressure. This phenomenon is a cornerstone of socialization for adolescents, as peer groups serve as one of the first major agents of socialization outside of the family. Peer pressure involves conforming to the behaviors, norms, and attitudes of one's peers, which can influence an adolescent's actions and facilitate social cohesion within the group.
Peer groups are incredibly important during adolescence, a time when individuals begin to develop an identity separate from their parents and assert more independence. They provide adolescents with opportunities to engage in different types of activities than those with their families and promote the learning of social norms. The correct answer to the question is 'c. Peer pressure', as it best describes how group dynamics influence adolescent behavior.
