While miskenning isn’t a common word in most vocabularies, you’re looking for something wrong or in error here, and mis should have you strongly considering choice A. Since bene in choice B is a good thing, that’s not applicable. The problem has nothing to do with heat or water so thermo and hydro are out of scope. And forti means to strengthen, so that isn’t applicable here either. Regardless of whether you’d use miskenning (which refers to an incorrect citation) in a sentence, its prefix shows that it’s the only applicable answer here.
