Compact.exe is the correct command line utility for compression in NTFS. This tool is specifically designed to compress files and directories, while the other options (compress.exe, zip.exe, and pack.exe) may be used for file compression in general, they are not specifically designed for NTFS. In addition, compress.exe is used for compression in FAT file systems, zip.exe is a utility for creating and extracting ZIP files, and pack.exe is a tool for package/unpackaging files, making them all incorrect for this question. Therefore, compact.exe is the most appropriate and specific choice for NTFS compression.
