Which of the following is an example of a primary group?

A primary group is characterized by close, personal, and enduring relationships. These groups are typically small in size and involve a high level of emotional intimacy, which fosters strong bonds among members. A small, close-knit group such as family exemplifies a primary group because members interact regularly, share personal experiences, and provide emotional support for one another. This deep level of personal engagement is the defining feature that distinguishes primary groups from others.

In contrast, a classroom of students represents a secondary group where interactions are more impersonal and focused primarily on educational objectives. A large organization is also a secondary group, as it typically consists of many individuals who may not know each other personally, and relationships tend to be more formal. Similarly, while a sports team does foster camaraderie and teamwork, it can sometimes represent a secondary group dynamic if interactions are predominantly performance-oriented rather than personal. Therefore, the small, close-knit group such as family stands out as the quintessential example of a primary group due to its intimate and personal nature.
