Which of the following best describes a primary group?

A primary group is characterized by close, personal relationships that are typically long-lasting and emotionally significant. These relationships are based on deep, strong ties, where members share a sense of belonging, loyalty, and emotional support. Family and close friends are classic examples of primary groups, as individuals within these groups often interact in a stable, intimate setting, allowing for open communication and a strong sense of inclusion.

The other options do not capture the essence of a primary group. Relationships based on mutual interests may describe different types of groups, but they do not emphasize the emotional bonds and stability that define primary groups. Large groups with limited interaction and temporary, role-focused interactions fall outside the definition of primary groups as they tend to involve less personal connection and are more focused on specific tasks or roles rather than sustained emotional engagement.
