What is a key limitation of GIF files?

Explanation:
GIF uses an 8-bit indexed color system, which means each image is described by a color palette of up to 256 colors. This design keeps file sizes small and works well for simple graphics with solid colors, but it limits color fidelity when the image has many colors or smooth gradients. Because of this 256-color cap, GIFs struggle with high-detail photographs, leading to loss of detail and visible color banding. That’s why this limitation is the best answer. It’s also worth noting GIFs can be animated, so a statement saying they cannot be animated isn’t correct; and they aren’t ideal for high-detail photography or for displaying a wide range of colors compared to formats like JPEG or PNG-24.
