Which of the following commands are used to get information on the proper use of ls? (Choose two.)

Answer options

• A. option ls
• B. usage ls
• C. manual ls
• D. man ls
• E. info ls

Correct answer: D, E

Explanation

The correct commands to obtain usage information for ls are 'man ls' and 'info ls'. 'man ls' opens the manual page for ls, providing detailed information, while 'info ls' offers a more detailed explanation in a different format. The other options, 'option ls', 'usage ls', and 'manual ls', are not valid commands for retrieving this information.
