关于宾语从句“that”的用法有一些疑惑需要请教

亲爱的敌人

Judge Lois Forer's study asks why do some litigants have a preferred status over others in the use of a public resource, the courts, which in theory are available to all but in fact are unequally distributed among rich and poor.

(A) do some litigants have a preferred status over others in the use of a public resource, the courts, which in theory are available to all but in fact are unequally distributed among

(B) some litigants have a preferred status over others in the use of a public resource, the courts, which in theory are available to all but in fact are unequally distributed between

(C) do some litigants have a preferred status over another in the use of a public resource, the courts, in theory available to all but in fact are unequally distributed among

(D) some litigants have a preferred status to another in the use of a public resource, the courts, in theory available to all but in fact not equally distributed between

(E) does one litigant have a preferred status over the other in the use of a public resource, the courts, in theory available to all but in fact they are not equally distributed among

I got this wrong as i did not understand the the role of 'do' here. Can some explain the reasoning when to avoid such mistakes.


比如说这道题，答案当然是B。但是楼主的疑惑是划线之前的部分，why引导的应该是宾语从句
，那么why之前为什么没有that啊？连接代词引导的宾语从句前不加that，但是why是连接副词不是连接代词，所以楼主已经糊涂了。。。。哪位大神解释一下啊，感激不尽
