Which image file format can support both animation and transparency?

The correct choice is GIF because this image file format is specifically designed to support both animation and transparency. GIF, which stands for Graphics Interchange Format, allows for the creation of simple animations by combining multiple frames into a single file, making it popular for web graphics and simple animated content.

Moreover, GIF supports transparency, allowing parts of the image to be transparent so that background colors or patterns can show through. This feature is particularly useful for overlaying images onto different backgrounds without a visible border, adding to its effectiveness in web design and digital art.

The other options do not have both features. For example, TIFF (Tagged Image File Format) can support high-quality images and transparency but does not support animation. JPEG (Joint Photographic Experts Group) is widely used for photographs, but it lacks support for transparency and cannot handle animation either. BMP (Bitmap) is a raster graphics format that does not support transparency or animation. Thus, GIF stands out as the only format that combines both animation and transparency effectively.
