What differentiates "primary" groups from "secondary" groups?

The distinction between primary and secondary groups is foundational in sociology. Primary groups are characterized by intimate, personal relationships where members engage in emotional and subjective interactions. These groups are typically smaller and foster a sense of belonging and loyalty, such as family and close friends. The close-knit nature of primary groups means that members have strong emotional ties and provide significant support to one another.

On the other hand, secondary groups are more formal and impersonal. They tend to be larger and often exist to achieve specific goals or fulfill certain functions, such as in workplaces or academic settings. Relationships within secondary groups are usually task-oriented and less emotionally intense, focusing on achieving objectives rather than fostering personal bonds.

Thus, option B accurately captures the essence of primary and secondary groups by noting that primary groups are informal with close relationships, while secondary groups are larger and more impersonal. This understanding is crucial for recognizing how social interactions differ based on the type of group one is part of.
