Which of the following is correct in the context of socialization of children?

In socialization theory, the family is considered the primary agent of socialization because it provides the child's first and most influential experiences in learning norms, values, language, and behaviors during early childhood. School, peers, and mass media are considered secondary agents because they come into play later and build upon the foundation laid by the family. The primary agent provides the initial framework while secondary agents expand and sometimes modify that framework.
