Final answer:
The term 'gender identity' refers to the gender a person most identifies with, which might differ from the sex assigned at birth. The correct option is a. gender idenity
Step-by-step explanation:
The term that refers to the gender that a person most identifies with is gender identity. Gender identity is one's internal, deeply held sense of being male, female, a blend of both, neither, or another gender entirely. This can be different from the sex one was assigned at birth.
For example, transgender individuals have a gender identity that does not match the sex they were assigned at birth, and cisgender individuals have a gender identity that does align with their sex assigned at birth. People who do not exclusively identify as male or female may describe themselves as non-binary. The correct option is a. gender idenity
