D. At least every third audit

Explanation: According to the AICPA Professional Standards of auditing. Testing the operating effectiveness of controls that appear to function as they have in past years and on which the auditor wishes to rely upon in the current year must be carried out at least every 3rd Audit.

effectiveness of specific controls. The auditor shall establish the continuing relevance of that

evidence by obtaining audit evidence about whether changes in those controls have

occurred subsequent to the previous audit.
