Final answer:
Girls' friendships in adolescence are more likely than boys' to focus on emotional closeness and support.
Step-by-step explanation:
Girls' friendships in adolescence are more likely than boys' to focus on emotional closeness and support (c). Research has shown that girls tend to prioritize and value intimate emotional connections with their friends. They often engage in deep conversations, provide support, and seek emotional closeness in their friendships. This is in contrast to boys, who may focus more on shared activities and interests (a), competition and dominance (b), or conformity to group norms (d).
