Which of the following statements best represents the difference between sex and gender as well as the concepts of gender binary and gender spectrum?

Sex refers to the biological differences between males and females, such as reproductive organs and chromosomes, while gender is about the roles, behaviors, and identities that society considers appropriate for men and women. The gender binary is a concept that divides people strictly into two categories: male and female, suggesting that everyone fits neatly into these roles. In contrast, the gender spectrum recognizes that gender is not limited to just two options; it exists on a wide range where people can identify anywhere along it, including non-binary or gender-fluid identities. For example, a person might be assigned female at birth but identify as male or non-binary, showing that their gender identity does not strictly match their biological sex. Understanding these differences helps us appreciate the diversity of human experiences and how society views gender.
