You are late.If you _____ a few minutes earlier,you _____ him.

题目

You are late.If you _____ a few minutes earlier,you _____ him.
A.come; would meet B.had come; would have met
答案是选择B,但我觉得A是正确的,其表达应该是属于与现在事实相反的情况,为什么说是属于过去事实相反的情况呢?
另外,请问在爱词霸沙友里如何提问的啊?

答案

你现在晚了,如果你刚才早点来,你刚才就看见他了.
事实上没早来,也没看见,故用过去时的虚拟.从句用had done,主句用would have done
