A monitor is an output device that displays information in pictorial form. A monitor usually comprises the visual display, circuitry, casing and power supply. Find the type of monitor given in the question which does not satisfy the definition of a monitor.

Complete step by step answer:
We are given to find which is not the correct type of Monitor from the given options.
First one is a Laser Monitor. There is no monitor such as a laser monitor.Second one is a CRT Monitor. A CRT Monitor is a cathode-ray tube Monitor which is a vacuum tube that contains one or more electron guns and a phosphorescent screen which is used to display images. It modulates, accelerates, and deflects electron beams onto the screen to create images.Third one is an LCD Monitor. A LCD Monitor is a liquid crystal display Monitor which is a flat panel display technology commonly used in TVs and computer monitors. It is also used in screens for mobile devices, such as laptops and tablets.Fourth one is an LED Monitor. A LED monitor is a light emitting diode display monitor that has more contrast, more brightness, consumes less energy, and has better response times. LCDs on the other hand are a lot cheaper, having lower response times, lower contrast and brightness rates but have more chance to prevent a possible burn-in.Therefore, Laser Monitor is not the correct type of Monitor.
Option A is the answer.

Note: Monitor is often used synonymously with computer screen or display. The monitor displays the computer's user interface and open programs, allowing the user to interact with the computer, typically using the keyboard and mouse. A desktop is a computer whereas a monitor is just a display screen. Do not confuse a monitor with a desktop.
