Which option is described as a lossless format for image files that supports animated and static images?

• A. A lossless format for image files that supports both animated and static images
• B. A lossy video format
• C. An uncompressed image format
• D. A lossy image format

Answer: (A)

A format that is lossless and can handle both animated and static images is describing GIF. GIF uses lossless compression (LZW) to store image data and can package multiple frames in a single file, which lets it display animations as well as single images. This combination—lossless compression plus support for animation—fits GIF exactly, which is why this option is the best choice. The other descriptions don’t match: a lossy video format is not primarily an image format and involves quality loss; an uncompressed image format isn’t defined by animation capabilities in a single file; a lossy image format contradicts the idea of lossless compression.
