Name one common file format for animating graphics in multimedia.

The choice of GIF as a common file format for animating graphics in multimedia makes sense because GIF (Graphics Interchange Format) is specifically designed to support animation. It allows for a sequence of images to be displayed in a loop, making it ideal for creating simple animations and graphics with reduced file sizes. The GIF format uses a form of lossless compression, which preserves the quality of the images, and it supports up to 256 colors, making it suitable for simple graphics and animations.

While JPEG and PNG are excellent formats for still images, they do not support animation capabilities. JPEG focuses on compressing photographs with varying color depths but does not allow for multiple frames or layers necessary for animation. PNG, while capable of supporting transparency and providing high-quality images, is also not designed for animation purposes. Likewise, PDF is a format primarily used for documents, which can include images and graphics but does not inherently support animation features like GIF does. Therefore, the GIF format stands out as the correct option for animating graphics in multimedia.
