What is characteristic of secondary groups in social interactions?

Secondary groups are characterized by being larger and more impersonal compared to primary groups. In these social structures, relationships tend to be more goal-oriented and temporary, often formed to achieve specific objectives or tasks. This contrasts with primary groups, which are typically smaller, characterized by close, emotional ties, and involve long-term relationships.

In secondary groups, interactions are often formal and may lack the deep emotional connections found in primary groups. For instance, work teams, school classes, or professional organizations exemplify secondary groups where the primary focus is on completing tasks rather than developing intimate personal bonds. Thus, the defining aspect of secondary groups is their impersonal nature and larger size, making option B the correct choice.
