I suppose for the sake of the question, Naegi-kun is probably the best candidate for marriage in terms of people I get along with, Celes-kun would be going off the cliff with the stipulation that she could be caught before hitting the ground, and I don't see why the third option is even a question because marriage renders it a moot point!
