The net use (Option D) command is used to manage network drives in Windows. It can be used to display and disconnect mapped network drives, making it the correct choice for removing unused network drives. * format (Option A) is used to format disks, not for managing network drives. * netstat (Option B) displays network connections but doesn't manage network drives. * diskpart (Option C) is used for disk partitioning, not network drive management. * rmdir (Option E) is used to remove directories, not network drives. CompTIA A+ Core 2 References: * 1.2 - Use the appropriate Microsoft command-line tool, including net use for managing network drives .
