Paleontologists believe that fragments of a primate jawbone unearthed in Burma and estimated at 40 to 44 million years old provide evidence of a crucial step along the evolutionary path that led to human beings.

(A) at 40 to 44 million years old provide evidence of

(B) as being 40 to 44 million years old provides evidence of

(C) that it is 40 to 44 million years old provides evidence of what was

(D) to be 40 to 44 million years old provide evidence of

(E) as 40 to 44 million years old provides evidence of what was
正确答案是D毫无疑问。但是我有个小小的问题：C项的estimate that为什么og解释说"that it is" creates an ungrammatical sentence?难道estimate that加从句表达不对吗？请NN指正，真心感谢^_^
