While editing a file in vi, an administrator realizes that the wrong file is being changed. Which of the following vi command sequences will allow the administrator to quit without saving any changes?

While `:Q` can be equivalent to `:q` in some vi variants, the exclamation mark `!` is crucial to force quit without saving, and `:q!` is the canonical form.

The `esc :q!` command sequence forces vi to quit without saving any modifications made to the file, which is useful when realizing the wrong file is being edited.

`:w!` saves the file forcefully but does not exit the editor.

`:wq!` saves the file and then quits the editor, which is the opposite of quitting without saving.
