Answer: D
Automated system's balancing would be the best way to ensure
that no transactions are lost as any imbalance between total
inputs and total outputs would be reported for investigation
and correction. Validation controls and internal credibility
checks are certainly valid controls, but will not detect and
report lost transactions. In addition, although a clerical
procedure could be used to sum and compare inputs and
outputs, an automated process is less susceptible to error.
