- A.
GIF

C. JPEGExplanation
JPEG is a lossy image format because it uses a compression algorithm that discards some data in order to reduce file size. This compression can result in a loss of image quality, especially when the image is heavily compressed. GIF, MPEG, and PNG are not lossy formats. GIF is a lossless format that supports animation, MPEG is a lossy format for video compression, and PNG is a lossless format that supports transparency.Rate this question:
