Which of the following statements is true regarding multi-report summaries for members of senior management...

Multi-report summaries are designed to provide senior management and the board with aggregated results across multiple audit engagements. To make them effective, internal audit functions typically rate findings (e.g., high, medium, low) so results can be compared and summarized efficiently.

Option A is incomplete because summaries are not just about describing audit work but about presenting meaningful insights. Option B (tables) refers to presentation style, not the key principle. Option C is incorrect because even if boards review individual reports, summaries provide strategic insights across engagements.

Thus, the correct answer is Option D.
