JPEG stands for Joint Photographic Experts Group, the international committee that developed one of the most widely used standards for digital image compression. The JPEG format was created to reduce the file size of digital photographs while maintaining acceptable image quality, making it ideal for storing and sharing images over the internet.
JPEG uses a lossy compression technique, which means some image data is permanently removed to achieve smaller file sizes. Users can choose different compression levels depending on the balance they want between image quality and storage space. Because of its efficient compression, JPEG is commonly used for photographs, web images, digital cameras, and social media platforms.
Although JPEG is excellent for photographs and colorful images, it is not the best choice for graphics containing sharp lines, text, or logos because repeated editing and saving can reduce image quality. Since the abbreviation is officially derived from the committee that developed the standard, Joint Photographic Experts Group is the correct expansion, making Option C the correct answer.
