Option C makes the most sense. The internal audit charter is what actually spells out the team's authority within the organization, so that's the strongest evidence to show when challenged about scope or fraud work. B (Standards) explains how audits should be performed, but doesn't grant authority by itself. Pretty sure this matches IIA guidance, but open if someone sees it differently.
I’d say D here, but is the question asking for the first step if the organization already has its vision and mission set? If that's the case, identifying stakeholders might not actually come first. Just want to clarify where in the process we are.
Why would "seniority of management" matter in the control framework? Isn't it more about clear accountability and making sure processes are supervised than just rank? Curious why some pick C over D.
