When the girl opens her eyes in a brightly lit room, her pupils shrink because the muscles contract.

The correct response is: Her pupils shrink because the muscles contract.

This happens because the bright light stimulates the iris muscles to constrict the pupils, reducing the amount of light that enters the eye to protect the retina from excessive brightness.
