Knowledge is ______.

• A. Energy
• B. Information
• C. Light
• D. Power

Answer: (D)

The main idea here is that knowledge translates into the ability to act and influence outcomes. When you know something, you can solve problems, make better decisions, and shape what happens around you, which is why knowledge is described as power. Energy and light describe physical quantities and illumination, not the capacity to act or control situations. Information is data that can become knowledge when you understand and apply it, but it’s knowledge that provides the actionable capability. So the best fit is power, since it captures the ability to influence, decide, and achieve goals through what you know.
