___________ the most important subject?-----English A Do you think which is B Which do you think is书上答案是B,但我感觉不大对,
答案肯定是B没错,这是英语疑问句的正确语序.
要注意的是,which才是主语,而do you think是插入语,也就是不影响句子构成,可以可无的成分,插入语都是放在句子中间的.

答案是B。这是一个英语语法，do you think在句子中成分为插入语，而which是主语。在句子中插入语应放在主语后面，所以是which do you think is. 希望能帮到您。望采纳，谢谢！

Which做主语 do you think 只是一个插入语句

Which 是疑问词，这是特殊疑问句，必须用疑问词提问
