Step-by-step explanation:
The most important factor to assess when determining a person's biological gender is chromosomal and anatomical characteristics.
Clothing and personal style, self-identified gender, and preferred name and pronouns are all important aspects of a person's gender identity, but they do not necessarily reflect their biological sex.
Chromosomal and anatomical characteristics, on the other hand, provide objective information about a person's biological sex. This includes factors such as visible genitalia, internal sex organs, secondary sex characteristics, and chromosomes.
