I don’t know the question.
A. what to answer
B. how to answer
C. to answer what
D. to answer how

A. what to answer(答案→)B. how to answerC. to answer whatD. to answer how解析：本题考查“疑问词＋不定式”结构的用法，这种结构可在句子中作主语、宾语、表语等。这种结构中，疑问代词须接及物动词或相当于及物动词的短语(who, which除外)，如：【误】 I don’t know what to talk.【正】 I don’t know what to talk about.但可以说：We haven’t decided who (which) to go. 我们还没定谁(哪个)去。这种结构中的疑问副词后要接不及物动词；若接及物动词, 要有动词的宾语。如：I don’t know how to talk. 我不知如何谈。I wonder if you could tell me how to do it. 不知您能否告诉我如何去做这件事。(不能说: ... how to do.)本题空格后已有宾语the question,故不能选A，只能选B。

我也是这个答案
