记住一个规则,主将从现即为主句将来时从句现在时态
相应的主句过去时态从句过去完成时
而且这里的HAD COME是对于过去时态的虚拟语气
即为如果她来了（对于过去时段的虚拟）她会碰到我
B是对于过去状态的强调
did come 如果她确实来了
但是此处只是对于过去时段的虚拟假设（假设她来了她肯定碰到我了）所以不可能是确定的语气
所以不是B

she would have met me.是虚拟语气，表明和过去事实相反，所以从句用过去完成时had done.
B 是强调，如果她的确来了

这是一个虚拟语气的句子。是对过去时间的虚拟，所以从句必须用had done

对过去时态的虚虚拟语气。从句用have done ,主句用would have done
