Masculinity and femininity are considered social constructs because they:

Concept

A social construct is a category or meaning created and maintained through shared norms, institutions, and social learning.

Because these meanings are socially produced, they can change across historical periods and cultural settings.

Application

Masculinity and femininity describe expectations about traits, roles, and behaviour associated with gender. Different societies and time periods attach different expectations to them.

Therefore, their variation across time and cultures is the feature that identifies them as social constructs.

Contrast

• “Independent of social interaction” excludes the social learning through which gender expectations are transmitted.

• “Vary across time and cultures” reflects the dependence of gender meanings on social and historical context.

• “Biologically universal and fixed” treats the meanings as unchanging biological facts rather than socially shaped expectations.

• “Remain identical across societies” denies the cultural variation expected of a social construct.

Cross-check

If masculinity and femininity were universal and fixed, societies would assign them the same meanings everywhere and at all times. Documented social and cultural variation is consistent with social construction.

Hence, the best-supported answer is “Vary across time and cultures.”
