• A. ISO Image
• B. IMG File
• C. Archive
• D. Boot Disk

Answer: (A)

An ISO image is a complete copy of everything stored on a physical optical disk, including the filesystem metadata and the data itself. It’s created by encapsulating the disc’s contents into a single file in the ISO format, which can then be mounted as a virtual drive or burned back to a CD or DVD to reproduce the original disc exactly as it was. This is why ISO images are commonly used for distributing operating system installers and other optical-disc content. While an IMG file can also represent a disk’s contents, it’s a more general term for a disk image and isn’t tied specifically to optical discs. An archive bundles files into a compressed package (like ZIP or TAR) and isn’t a faithful, bootable image of a disc’s structure. A boot disk refers to a disk prepared to start a computer, which may be created from an image but isn’t itself the image of the disc.
