The most likely explanation why the auditor’s examination cannot reasonably be expected to bring all illegal acts by the client to the auditor’s attention is that

a. Illegal acts are perpetrated by management override of internal control.

b. Illegal acts by clients often relate to operating aspects rather than accounting aspects.

c. The client’s internal control may be so strong that the auditor performs only minimal substantive testing.

d. Illegal acts may be perpetrated by the only person in the client’s organization with access to both assets and the accounting records.
