Which command allows you to both display the output of the who command on the screen and save it simultaneously into a file called user.lst?

Explanation

Option A uses the pipe with tee to display the output and write it to user.lst at the same time. Option B redirects output only to the file without displaying it. Option C appends output to the file but does not show it on the screen. Option D incorrectly uses input redirection. Option E is not a valid command.
