Which statement best describes a raster image?

• A. It is composed of a grid of pixels.
• B. It is defined by mathematical curves.
• C. It is a vector graphic.
• D. It is primarily used for audio.

Answer: (A)

Raster images are composed of a grid of pixels, with each pixel holding color information that together forms the picture. When you zoom in, you can see the individual colored squares, a phenomenon called pixelation that shows how rasters store image data. This stands in contrast to vector graphics, which are defined by mathematical curves and shapes that scale without losing quality. The statement about being defined by mathematical curves describes vector graphics, not raster images. The option about audio isn’t related to images, so it doesn’t fit.
