Final answer:
The statement in question is an example of a family rule option (b). These rules help structure behavior and are influenced by broader societal norms and values, which also change over time.
Step-by-step explanation:
The statement "One must never show anger" is an example of a family rule. This type of rule is often set by the authority figures within a family, like parents, to guide behavior and maintain order and civility.
Family rules play a critical role in the socialization process by teaching children the expectations for behavior within not only the family unit but also in society at large, illustrating cultural norms, values, and attitudes.
It is important to understand that while these rules and norms can be influential, they are also shaped by the wider societal context and can change over time.
For instance, disciplinary actions that were once common and accepted can evolve to become taboo and considered unacceptable in later historical periods, as society's views on child rearing and behavior evolve.
