Who is the subject of “She Dwelt Among the Untrodden Ways?”

I think the correct answers from the choices listed above are the first and second options. The effect of repetition in the last stanza of Robert Frost's "Stopping by Woods on a Snowy Evening would be that it shows the distance that the speaker has to travel before he finishes his job and emphasizes that the speaker has accepted his responsibilities in life. Hope this answers the question.
