选C
这是一道主从句时间不一致的虚拟语气条件句,从句对过去进行虚拟用had done 主句对现在进行虚拟用would do 所以选C
C. would be 这是与过去事实相反的虚拟语气
A 错综虚拟语气If you had studied harder in those day,与过去事实相反，如果你过去学习更努力， 主句中now. 应该用现在时
答案是C，因为这是if引导的条件状语从句，从句用一般现在时，主句用一般将来时。

与过去事实相反: 条件从句： If +主语+had done， 主句： ...

B. could have been。理由：虚拟语气，和现在的事实相反（因为有now 这个词），即使条件从句中使用了过去完成时，主句仍使用 would be。
如果是和过去的事实相反，就要：从句使用过去完成时，主句使用完成时：If I had been born 100 years earlier, I would have been a man like Sun Yat-sen lead...
