Question

一道初三英语选择题

Do you know ____ in China?
A.who is the first spaceman
B.when did the first spaceman get into space
C.how many spacemen had gone into space
D.where the first spaceman live
问题补充：
我知道A和B肯定不对，因为语序不正常，那么C和D哪个对呢？
请说明理由，若被采纳另加50分，谢谢！
（where可是地点副词啊，可以省略介词） C是不是不应该用过去完成时啊，因为主句是know一般现在时，老师说先有一个过去时，才能有过去完成时，在这里对不对呢？
