It was very kind of you to do the washing-up, but you ___ it.
A.mustn't have done B.wouldn't have done
C.mightn't have done D.didn't have done
A.mustn't have done B.wouldn't have done
C.mightn't have done D.didn't have done
A好像不太对吧？mustn't表示禁止
我觉得像是C “本可以不必做”
B
选A.mustn't have done
肯定边成否定成为本不必
b不应该
c不可以
显然不对
赞成A的
选D，肯定对，是不必做的意思
A：必定没做
B：可能没做
C：说不定没做
A is the correct answer
