01 What does a monitor display?
Answer and explanation
Correct answer: A. Visual output of the computer
Explanation: A monitor is an output device because it presents the computer’s processed results in a visual form. It can show text, photographs, graphics, menus, and videos on its screen. Electricity is required to operate the monitor, but electricity itself is not the displayed result. A paper file is not a screen output, and water level is unrelated. Thus, option A correctly identifies the monitor’s function.
