The correct answer is Option 3: Membership of a professional group. Here is the detailed explanation for each option:
Membership of family (Option 1): This is an example of community identity. Family membership is a fundamental aspect of social identity, as families often share common values, traditions, and cultural practices. Families can be seen as small communities with their own norms and identities.
Membership of religious group (Option 2): This is also an example of community identity. Religious groups often have shared beliefs, rituals, and practices that define their community. Membership in a religious group can be a significant part of a person's identity and sense of belonging.
Membership of a professional group (Option 3): This is not an example of community identity. While professional groups can have a sense of camaraderie and shared interests, they are typically defined by occupational roles and economic functions rather than social or cultural identities. Professional groups are more about shared skills, expertise, and career-related activities rather than communal or cultural bonds.
Membership of caste group (Option 4): This is an example of community identity. Caste groups, particularly in the context of India, have historically defined social hierarchies and cultural identities. Membership in a caste group often comes with specific roles, traditions, and social expectations that contribute to a person's community identity.
Therefore, the correct answer is Option 3: Membership of a professional group, as it does not fit the definition of community identity in the same way that the other options do.
A professional group is not based on inherent social identity; it is based on skills and occupation.
