The independence of the internal audit activity can be threatened if the annual budget for the internal audit activity is approved by the chief financial officer (Option B). This situation creates a potential conflict of interest because the CFO has a significant influence over the internal audit activity ' s resources, which may impact its ability to operate independently and objectively. According to the IIA Standards, Standard 1110: Organizational Independence, the internal audit activity must be free from interference in determining the scope of internal auditing, performing work, and communicating results. Functional reporting to the board and administrative reporting to the CEO (Option A) supports independence, while outsourcing and providing consulting services (Options C and D) do not inherently threaten independence as long as proper safeguards are in place.
