Calvert City's Police Officers Need to Pass a Test as a Part

Calvert city's police officers need to pass a test as a part of their performance evaluation to get promoted.It was recently discovered that female officers taking the test scored significantly lower than male officers.Thus,the number of female officers being promoted was much lower than the number of male officers being promoted.If it was not evident that the test was the cause for the bias,the city's decision would cause:

A) disparate treatment discrimination against male officers.
B) liability under bona fide occupational qualification.
C) liability under retaliatory discharge.
D) disparate impact discrimination against female officers.
