(d) managing disk space, performing backup, changing attributes of a file

I have been asked this question in an interview for job.

This question is from Administrator Specific Commands and Privileges topic in chapter Essential Shell Programming of Unix

Answer 1

Correct choice is (d) managing disk space, performing backup, changing attributes of a file

The best I can explain: superuser or the root user has access to vast powers like he/she is responsible for managing the disk space, performing backups, changing attributes of files, maintaining user accounts etc.
