Which is correct for "English".  If you type C-\, Emacs will ask you
what input method to turn on.  If there's a default input method,
Emacs doesn't ask.  Try:

  M-x set-language-environment RET French RET

Then type C-\ and Emacs will turn on the default input method without
asking.

Your question was about the default input method.

They are not the default in this language environment.

Again, you asked about the _default_ input method.

If you are now asking about a non-default input method you invoked by
name, then you can get it from current-input-method (but only as long
as the input method is active), or from default-input-method.
