The choice of JPEG as the correct answer is rooted in its widespread use for compressing digital images. The JPEG format employs lossy compression, which significantly reduces the file size by selectively discarding some image data, which is particularly effective for photographs and images with many colors and gradients. As a result, JPEGs maintain a good balance between image quality and file size, making them ideal for web use and digital photography.

While other formats listed, such as TIFF, PNG, and BMP, may also store images, they do not primarily focus on image compression in the same way. TIFF is often used for high-quality images and supports lossless compression methods, thus maintaining image fidelity but resulting in larger file sizes. PNG is designed primarily for graphics and images that require transparency and uses lossless compression, which means that the original image quality is preserved but it does not achieve the same level of compression as JPEG. BMP is an uncompressed format that usually results in very large files and does not employ any form of compression, making it less practical for general use compared to JPEG.

Therefore, the selection of JPEG reflects its core functionality in image compression, making it the most suitable format for that specific purpose.
