When an internal auditor has audited the same department repeatedly, familiarity threat is a significant concern. The IIA Standards emphasize maintaining objectivity and avoiding circumstances that could impair the auditor's unbiased attitude. Auditing the same department annually for several years can lead to familiarity, which can compromise the internal audit activity's independence and objectivity (Option B).
According to Standard 1130: Impairment to Independence or Objectivity, auditors must avoid auditing areas where repeated engagements might lead to a lack of objectivity due to familiarity.

According to IIA guidance, the chief audit executive should review the quality assurance and improvement program of the internal audit activity progressively on a day-to-day basis. This continual review ensures that the internal audit activity remains effective and aligned with the organization's objectives and adheres to professional standards, thereby maintaining and enhancing the value provided by the audit function.
IIA standards related to the quality assurance and improvement program, which advocate for ongoing monitoring to ensure the effectiveness of the internal audit activity.

In an internal audit charter, the statement most directly related to describing the responsibilities of the internal audit activity is that the Chief Audit Executive (CAE) shall report periodically on the performance of the internal audit activity relative to its plan. This statement explicitly outlines a fundamental responsibility of the CAE and the audit activity, focusing on accountability and performance measurement against the planned objectives.
IIA standards related to the roles and responsibilities included in the internal audit charter, which typically define the reporting obligations of the CAE as a reflection of the internal audit activity's duties and performance.

Using information from an engagement to assist a friend's business violates the IIA Code of Ethics, as it breaches confidentiality and objectivity. Internal auditors must maintain impartiality and not misuse information for personal or external advantage.

Reporting functionally to the CEO can promote internal audit objectivity. This arrangement helps ensure that the Chief Audit Executive (CAE) has the necessary independence from the areas being audited and sufficient authority to carry out audit responsibilities effectively. While ideally, the CAE should report functionally to the board for maximum objectivity, reporting to the CEO is a common practice that supports operational independence from direct operational management, such as the CFO or COO.
