What do the 3 RCA connectors in component video represent?

Brightness and 2 for color
Audio and video
Video only
Power, audio, and video

The correct answer is: Brightness and 2 for color

The 3 RCA connectors in component video represent brightness and 2 for color. This is because component video divides the video signal into three separate components red, green, and blue. Each of these components is responsible for a portion of the image displayed on the screen. By separating the brightness and colors into separate channels, component video allows for a higher quality and more accurate reproduction of colors on the screen. Option B is incorrect because it combines audio and video into one channel, while component video separates them into three channels. Option C is incorrect because it only represents the video signal, while component video also includes two separate signals for color. Option D is incorrect because it includes a power signal, which is not necessary for component video.
