I think the correct answer from the choices listed above is the second option. The word that has a neutral connotation would be multilevel. Connotation is the associated or secondary meaning of a word or expression in addition to its explicit or primary meaning. Multilevel in any definition would not relay any good or bad feeling to it. Hope this answers the question.
