When a file owner's account is deleted, which of the following statements is true regarding the file?

When a file owner's account is deleted, the file remains on the filesystem, and the ownership information attached to that file does not automatically update with new user data. Specifically, the User Identifier (UID) of the former owner of the file will still be visible when listing the file's details. This allows the system to maintain a reference to the file's original ownership, despite the user account being deleted.

In this context, while it's true that root, being the superuser, has the ability to access all files, the statement about root being the only person who can access the file does not fully capture the nuances of file permissions. Other users may also have access depending on the file's permission settings. The file can still be moved or renamed; the permissions remain unchanged by mere account deletion unless modified by an action taken by a user or a process. Therefore, the correct understanding that persists regarding the file's account deletion is that it retains the UID of the former owner, which can be helpful for administrative purposes or auditing.
