Which term describes images composed of grids of pixels with fixed resolution that cannot be resized without losing quality?

• A. Vector graphic
• B. Raster image
• C. Bitmap graphic
• D. Raster graphic

Answer: (D)

Raster graphics are images built from a grid of individual pixels, each carrying color information, and they have a fixed resolution. When you resize such an image, you're effectively spreading the same pixels over more space, which makes the image look blurry or blocky because the individual pixels become visible. This is why raster graphics lose quality when scaled. In contrast, vector graphics are created with mathematical paths, so they can be scaled to any size without losing clarity. A bitmap graphic is another term for a raster image, but the standard term used here is raster graphic.
