求助一题prep 语法题

A recent poll of elected officials suggests that candidates, when in the midst of a tough campaign, often make statements about an opponent that they may not think is true.

(A) is
(B) are
(C) to be
(D) of as
(E) it is




OA 是 B， 但是我选了C, 因为我听到这个句子第一反应就是 think to be... ？ 为什么B 不对呢？没有这种用法吗？

这里分享一个帖子，这个句型是嵌入式关系分句。

Eg：
In his breast-pocket he hada patch of scarlet, which i suppose was the paper cap serving as ahandkerchief.
注意两点：
1）从句which was the paper cap serving as a handkerchief 首先是 patch of scarlet的定语从句。         
2）从句which（patch of scarlet） was the paper cap serving as a handkerchief 也是i suppose 的宾语从句，即I suppose （that）the patch of scarlet was the paper cap serving asa handkerchief 。
综上所述，当一个定语从句同时是另一个主谓结构的宾语从句是，就可以写为嵌入式关系分句

就像这个例子一样，
that are true首先是statements about an opponent的定语从句
然后they may not think是一套新的主谓， 后面跟的是 that（statements about an opponent）are true这个宾语从句！
如果是that（statements about an opponent）to be true的话，不完整，不能做宾语从句。

PS：Ron说过that可以修饰n+介词短语（该介词短语对该n有直接修饰作用）
