Explanation

restore is the companion command to dump - they form a paired system for Unix/Linux filesystem backups, where dump archives data and restore retrieves it, making C the correct answer.

Why the distractors are wrong:

• A. extract - not a standalone Unix backup utility; extract is a subcommand in some tools (like tar --extract) but has no relation to dump backups.
• B. cpio -d - cpio is a separate archiving tool entirely; -d creates directories during extraction, but cpio cannot read dump format archives.
• D. udump - this doesn't exist as a standard command; it's a plausible-sounding distractor playing on the dump/udump confusion (some systems have dump variants, but udump is not a restore tool).

Memory tip: Think of it as a two-word pair - dump/restore - just like backup/recover. If dump puts data away, restore brings it back. The symmetry of the verb makes it easy to recall.
