OE


Altruistic (unselfish) and magnanimous (coming from a nobility of character) are both positive moral descriptions for an action. Their positive connotations fit the context of the sentence, which requires a positive first half to counter the negative second half, as indicOd by the keyword "while." The remaining answer choices all carry negative connotations: sanctimonious refers to a hypocritical devoutness to something; reprehensible actions demand or deserve reproof; raucous is boisterous; and refractory actions are unmanageable ones.
