Answer : 2. "color monitor"
Explanation :
a color monitor is a type of display that can adjust and display output by manipulating the Red, Green, and Blue (RGB) radiation. In a color monitor, pixels are made up of red, green, and blue sub-pixels, and by varying the intensity of these colors, a wide range of colors can be displayed on the screen. Adjusting the intensity of RGB radiation allows the monitor to display different colors and shades, providing a full spectrum of colors to the viewer. This technology is commonly used in computer monitors, television screens, and other displays to produce vibrant and accurate color representations.
