Chkdsk
Command.com
Format
Fat

The correct answer is C. Format.

Format is a command-line utility that can be used to create a new file system on a disk, or to erase the contents of an existing file system. When you format a disk, the operating system creates a new root directory and FAT (File Allocation Table) on the disk. The root directory is the main directory on the disk, and it contains all of the other directories and files on the disk. The FAT is a table that keeps track of where all of the files on the disk are stored.

Chkdsk is a command-line utility that can be used to check the integrity of a disk and to fix any errors that it finds. Command.com is the command interpreter for the MS-DOS operating system. Fat is a file system that was used on early versions of MS-DOS.
