The correct option is
A Devised
'Contrived' means too obviously designed to produce a particular result, and therefore not seeming to happen naturally. E.g. The movie's plot was much too contrived. 'Devised' means to invent a plan or system using imagination and thinking. 'Defaced' means to damage and spoil the appearance of something by writing or drawing on it. 'Defected' means faulty. 'Deferred' means to delay something until a later time.
Thus, option A is the most similar in meaning to the given word.
