Final answer:
The correct factors influencing the moral development of adolescents are family, peers, media, and culture. These influences shape adolescents' burgeoning moral and ethical values system and impact their decision-making and behavior.
Step-by-step explanation:
The moral development of adolescents is influenced by various factors such as family, peers, media, and culture. During adolescence, individuals develop their own system of moral and ethical values. Family is often the primary influence, as it shapes early views on religion, work, and education. As adolescents seek to form their identity, they also become more emotionally detached from their parents and increasingly influenced by their peers. Peer acceptance, in particular, is a driving force for many teens, which can shape their moral choices. Additionally, media exposure and cultural norms play pivotal roles in outlining what is perceived as morally acceptable behavior. Therefore, the correct choice reflecting these influences is 'A. Family, peers, media, and culture'.
