Which chromosomes are the sex chromosomes in humans?

Explanation:
The main idea is that the sex chromosomes determine human sex. In humans, the sex chromosome pair is X and Y. Females typically have two X chromosomes (XX), while males have one X and one Y (XY). The Y chromosome carries genes like SRY that drive male development, and the X chromosome carries many essential genes needed by both sexes. The other options refer to autosomes, which are the non-sex chromosomes, so they don’t determine sex. Therefore, the sex chromosomes are X and Y.
