A is wordy, confidence in ... keeping in control of ... C confidence for..... is unidiom, and that clause has no object. Also, the tense of would is wrong. D and E use unidiom structure, be kept control of by...., and compared with B, passive voice is not recommended as well.
BTW, in B, that clause is appositive clause of confidence.
