PREP中的一道题目，that引从句难道不优于of

shixiaoliu1986

The loan company announced it would soon lend money to borrowers with proven records
of their not paying back their loans on time, collectively known as the subprime lending
market.
A. of their not paying back their loans on time,
B. of not paying back their loans on time, a group
C. of not paying back their loans on time, with such a group
D. that they do not pay back their loans on time,
E. that they do not pay back their loans on time, such a group
答案选择B，我认为是E，我有两个问题1、that引导难道比of修饰更差？ 2、E中的such是多余的吗？有和没有有区别吗？谢谢啦～

要是 加个 such，变成 such a group collectively known as the subprime lending market。这么样一个被认为有广泛特的群体，例如次贷市场。意思不对。
原句的意思是 这样一个团体因次贷市场而被广为人知。

另 我感觉 that 和 of 应该都可以，请nn解释吧
