Answer:
The fraud was discovered Option D: The operations manager found a check made payable to Phillips while searching Phillips' desk for some accounting records.
Step-by-step explanation:
In the given case study, Ernie Phillips had got a job as a 'controller'. He had started writing checks to himself other than the payroll checks.
This fraud can be discovered when the operations manager found a check on Phillips desk which was payable to himself and it was other than the payroll check. Thus, Option D is the statement as an answer.
Cancelled checks do not have to do anything with the fraud, as per Option A, because cancelled checks are never cleared in the bank. The receiver doesn't usually receive a call before check clearance. So, Option B is also incorrect. No error was there in the check as stated in Option C.
