Answer: D
To ensure that the programmer could not have a check
(cheque) generated, it would be necessary for someone to
confirm all of the checks (cheques) generated by the system.
Range and logic checks could easily be bypassed by a
programmer since they are privy to the controls that have
been built into the system. The review of the accounts
payable reports by data entry would only identify changes
that might have been made to the data input. It would not
identify information that might have been changed on the
master files. Reviewing reports for checks (cheques) over a
certain amount would not allow for the identification of any
unauthorized low value checks (cheques) or catch alterations
to the actual checks (cheques) themselves.
