I'm Marie, aren't I or I'm Marie, am not I or I'm Marie, amn't I? What is correct!?

Solutions
This is a good question. For speakers of most varieties of English, "I'm Marie, aren't I?" would be most common and considered "correct" despite the irregular use of "are" in the so-called tag question (normally, the auxiliary verb in the tag question is the same as in the main clause; see https://blabmate.com/article/which_has_the_correct_tag_question_ahmed_is_clever_isnt_it_or_ahmed_is_clever_dont_you/96/).
"I'm Marie, am I not?", where not only is "am" used but also, again contrary to pattern, the negative particle "not" is not contracted with the auxiliary but is placed *after* the pronoun subject of the tag question, is possible but it is used in limited contexts, especially in very formal or very emphatic usage.
And the tag in "I'm Marie, amn't I?" is heard occasionally, but it appears to be limited to only certain regional dialects of English even though it is "regularly" formed, i.e., with the auxiliary "am" contracted with "not" followed by the subject "I." Again, far more English speakers would use "aren't I" in this case (or even the non-standard "ain't I").
