The correct answer is C. Pixels.
A pixel is a tiny dot that makes up an image on a computer screen. The word “pixel” is a portmanteau of “picture” and “element.” Pixels are arranged in a grid, and each pixel has a specific color and brightness. The number of pixels in an image determines its resolution. A higher resolution image has more pixels, which results in a sharper image.
Pixels are used in a variety of devices, including computer monitors, televisions, and digital cameras. They are also used in some types of printing, such as inkjet printing.
Option A, “colored spots,” is incorrect because it does not accurately describe the nature of pixels. Pixels are not simply colored spots; they are tiny dots that have a specific color and brightness.
Option B, “pixies,” is incorrect because it is not a commonly used term for pixels. The term “pixie” is sometimes used to refer to small, imaginary creatures, but it is not typically used to refer to pixels.
Option D, “none of these,” is incorrect because it is not the correct answer to the question. The correct answer is C, “pixels.”
