We have two rooms ( ),but I can't decide ( ) .Ato live,to choose which one Blived,choose which one Clive,which Dto live in,which one to choose 答案是选的D,但为什么A错呢?疑问:句尾还加in,有何目的?后半空有要用那种语序?尽量详细点,我是英语初学者

我们有两间可供居住的房子,但是我不知道选择哪一间.
Live表示居住时为不及物动词,后面要加介词in再接宾语,live in:居住在某地.
Which是疑问代词 应该放在句首,which one to choose 是正常语序.
