5. _______, we were not going to make any concessions to his unreasonable demands.

a. What may come b. Come what may
c. May what come d. What come
要说明原因啊~~~~~~~~~~~~~~

不要乱猜啊，正确答案为b，就是不知道原因！！！！！！！1

Come what may 即 We didn't care what may come.

不管后果如何，我们不会对他无理的要求退让。

因此答案为B

C May引导的倒装

选C May在这里表示强烈语气， May what come相当于 Whatever comes

你好！ Come what may 意思是: I don't care what may come. (我才不管后果如何呢 的确应该选B，口语话的一个词组 仅代表个人观点，不喜勿喷，谢谢。
