The correct answer is: D. All of the above
The ls -l command is a Linux command that lists the contents of a directory. It can also be used to display detailed information about a file, such as its owner, group owner, size, and modification date.
The following is an example of the output of the ls -l command:
-rw-r--r-- 1 user group 1024 Jan 1 00:00 file1
-rw-r--r-- 1 user group 2048 Jan 1 01:00 file2
The first column of the output shows the permissions of the file. The second column shows the owner of the file. The third column shows the group owner of the file. The fourth column shows the size of the file in bytes. The fifth column shows the date and time when the file was last modified.
The ls -l command is a powerful tool that can be used to view and manage files on a Linux system.
