Answer:
Option D
Explanation:
The Eva Opened a "Women's-Only Health Spa". it is expected to have women as majority employees due to the privacy and gender management. She already has 4 employees out of 20 as males, not that she does not have males as employees.
She probably rejected jack because that role, (Locker room attendant), will require sensitive responsibilities which are not stated in the passage. obviously, she would require a female for that role.
She can defend her case by showing that female is a bona fide occupational qualification for the job, based on the reason i stated above.
The best option is Option D
