I have been asked this question during an interview.

I'm obligated to ask this question of Administrator Specific Commands and Privileges in chapter Essential Shell Programming of Unix

Answer 1

Correct answer is (d) -k

To explain I would say: The df (disk free) command reports the amount of space available for each file system separately. -k option is used with df command for displaying the total amount of disk space in the file system in terms of Kilobytes.
