A Correct answer
Explanation

LIST EXPIRED shows files marked EXPIRED after CROSSCHECK - meaning the backup record exists but the file is missing. DELETE EXPIRED would remove these records. DELETE OBSOLETE removes backups older than retention policy. CHANGE UNCATALOG removes records from the repository entirely.
