Which term labels the concept of testing controls at multiple levels such as Low, Medium, and High?

• A. Normal / Abnormal
• B. Positive / Negative
• C. Low / Medium / High
• D. Levels of Controls

Answer: (D)

Testing controls at multiple levels uses a framework that labels the controls as different levels of stringency or risk to verify performance across a range of conditions. The term Levels of Controls is the best fit because it explicitly names this approach—having distinct levels (low, medium, high) to test and monitor how a process or instrument performs under varying scenarios. Other terms describe results or separate ideas (Normal/Abnormal are result statuses; Positive/Negative describes outcomes), or merely name the individual levels without capturing the structured labeling concept.
