The answer is d) Sex is biological; gender is social.
This option is incorrect because it conflates the concepts of sex and gender. While sex is indeed genetic, gender is not limited to primary and secondary sex characteristics but encompasses a broader range of social and cultural roles and identities.
This option is incorrect because it reverses the widely accepted definitions. Gender is generally understood as a social construct, while sex is biological.
This option is incorrect because it suggests that both sex and gender are primarily genetic, which is not the case. Gender is more about social and cultural roles, while sex is biological.
This option is correct. In sociology, sex refers to the biological differences between males and females, such as chromosomes, hormonal profiles, and internal and external sex organs. Gender, on the other hand, refers to the roles, behaviors, activities, and expectations that society considers appropriate for men and women.
