哪位知道of和that的修饰区别

最近总在碰见of和that的修饰问题。

下面有一道

Retail sales rose 8/10 of 1 percent in August, intensifying expectations that personal spending in the July-September quarter more than doubled that of the 1.4 percent growth rate in personal spending for the previous quarter.

A.   that personal spending in the July-September quarter more than doubled that of

B.   that personal spending in the July-September quarter would more than double

C.   of personal spending in the July-September quarter, that it more than doubled

D.  of personal spending in the July-September quarter, more than doubling that of

E.   of personal spending in the July-September quarter, that it would more than double that of

正确选项是B,后面的那个double是形容词还是动词。谢谢大家

n. + of + n.  强调名词

n. + that + 从句  强调that后整句的内容，这里是要说明expectations的内容，所以用that更合理。

double是动词。
