Which of the following is not an input device?

Explanation:
The key idea here is distinguishing input devices from output devices. An input device sends data into the computer: the keyboard types letters and numbers, the mouse provides coordinates and clicks to control the cursor, and a scanner converts physical documents into digital data. A monitor, by contrast, is used to display information that the computer already produced, so it presents output rather than taking input. (Some displays can be touch-enabled, which adds input capability, but in standard classifications a monitor is considered an output device.) That’s why the monitor is not an input device.
