Where is the correct position of "with" in this question?

[misu]

Which of the following two versions of question is correct?

1. Who's she in Oxford with?
2. Who's she with in Oxford?


or would it be much better the follwoing way:

3. With who (whom) is she in Oxford?

 

[misu]

But which one sounds better/more natural to you?

 

[GoesStation]

Number three is unnatural. Nobody would use either version.

GS's comment aside, "With whom is she in Oxford?" is grammatically correct. It might be used by someone trying to sound very formal/posh! It is, however, unnecessary to use the construction in everyday modern speech.

Please don't change or add to your original question after it has received a response, misu. I had to change my first response slightly after you changed your question.

Sorry about that

By the way. A spontaneous question has just occurred to me. It's about my previos question "which one sounds more natural to you"

I am wondering why this sentence doesn't need the auxiliar "does" as in for example "which one does he prefer".
Maybe because of the verb "sound"?
It might apply to "taste", "smell" and "look" as well.
