这问题提得可是太好了！
一般来说，陈述句和简略问句的情态动词或助动词一般要保持一致
must作为必须来讲的话，对应的就是must not

但也有特殊情况
must have done作为对过去某一时间的事情推测时，对应的就是did not
must have done作为对发生在过去但对现在造成影响的动作进行推测时，
对应的是have not
must not表示禁止时，对应的就是may
然后分析题干，
I must have done something wrong yesterday,___?
中yesterday作为特指，相当于对现在有影响
所以本题答案选B
综上所述
第一题选D
第二题选B
