Senior management has requested that the internal audit function perform an operational review of the telephone marketing operations of a major division and recommend procedures and policies for improving management control over the operation. The internal audit function should:
a. Accept the audit engagement because independence would not be impaired.
b. Accept the engagement, but indicate to management that recommending controls would impair audit independence so that management knows that future audits of the area would be impaired.
c. Not accept the engagement because internal audit functions are presumed to have expertise on accounting controls, not marketing controls.
d. Not accept the engagement because recommending controls would impair future objectivity of the department regarding this client.
