Assertion (A) is true but Reasoning (R) is not correct.

Primary groups, such as family, caste, and religion, are pre-existing formations that individuals are typically born into, fostering face-to-face interactions, close proximity, and emotional bonds. These groups play a fundamental role in shaping values and ideals during early development. In contrast, secondary groups, like political parties, are joined by choice, characterized by more impersonal and indirect relationships.
