Final answer:
Every group within the Navy must adhere to its core values; therefore, the correct answer is 'None.' The group that serves as a standard for one's behavior is a 'Reference group.'
Step-by-step explanation:
No group within the Navy, whether officers, enlisted personnel, or senior leaders, is exempt from adhering to the Navy's core values. These core values are a fundamental set of principles that guides the behavior and decisions of all members within the Navy. As such, the answer to the question is d) None.
Regarding the definition of a group whose values, norms, and beliefs serve as a standard for one's own behavior, the correct answer is c) Reference group. A reference group is a type of group that people compare themselves to or look up to for guidance in setting their own standards and behaviors. This group influences a person's attitude and behavior. Examples of reference groups include peers, family, celebrities, or any other group whose values one admires and wishes to emulate.
