Answer:
D) Managers who performed well on the tests performed poorly in their roles.
Step-by-step explanation:
The whole idea behind a complex selection process is to be able to select the best possible candidate to fill an open position. If the managers that were selected using this process performed poorly on their jobs, that means that the selection process is not working properly. Obviously only those who perform well on the tests are hired, so there is no way of knowing if those who performed poorly would have been better managers.
