D Correct answer
Explanation

The 'df' command (Disk Free) displays the amount of available and used disk space on mounted filesystems. This is different from 'du' which shows usage by specific directories. The 'tar' command is for archiving files, while 'uspace' and 'space' are not standard Unix/Linux commands.

AI explanation

df (disk free) reports available and used space on mounted filesystems, showing overall capacity and free space per disk/partition/mount point. du reports space consumed by specific files/directories (usage, not availability), tar is an archiving utility unrelated to reporting free space, and 'uspace' is not a real command. df is the correct, standard tool for checking how much disk space is available on the system.
