"ls" shows only visible files whereas "ls -a" also displays those starting with a dot. Given the question doesn't that make your answer the correct one?

  It accepts ls -a as and answer and ls -l but not ls -al

  `la -A` will also show hidden files but excludes the "." and ".." I prefer that way in theory but a capital "A" is not as quick/easy to type.
