Which of the following best demonstrates the board of directors' governance over internal control?

The board of directors' primary governance role is oversight, not direct management. Succession planning for the CEO and key executives is a critical oversight function that directly establishes the "tone at the top." By selecting, evaluating, and planning for the replacement of senior leadership, the board ensures that competent and ethical individuals are in place to design, implement, and maintain the organization's system of internal control. This action is a fundamental component of the control environment, which is the foundation for all other components of internal control, making it the best demonstration of governance.

A. This is incorrect because senior management, not the board, is directly responsible for developing and implementing the internal control system. The board's role is to oversee this process.
B. This describes a poor governance structure. Best practices require a majority of independent, non-executive directors to ensure objective oversight and mitigate conflicts of interest.
C. The audit committee chair must be an independent, non-executive board member. The chief audit executive (CAE) reports functionally to the audit committee but cannot chair it, as this would impair independence.

Standard 2110: Governance, Page 13: "The internal audit activity must assess and make appropriate recommendations to improve the organization’s governance processes for... Ensuring effective organizational performance management and accountability."
