TTGWD4-Q39,到底考什么呢？C为何不对？

TTGWD4-Q39.

Unearthed in China, fossils of feathered dinosaurs offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds.

A.      offer the most dramatic evidence yet discovered of the close evolutionary relationship between dinosaurs and birds

B.      offer evidence more dramatic than what has yet been discovered of the close evolutionary relationship between dinosaurs and birds

C.      offer more dramatic evidence of the close evolutionary relationship than any yet discovered between dinosaurs and birds

D.      have offered the most dramatic evidence of the close evolutionary relationship between dinosaurs and birds

E.       have offered more dramatic evidence than any that has yet been discovered of the close evolutionary relationship between dinosaurs and birds

key is A

我认为C的语序不对,把than any yet discovered插在the close evolutionary relationship和between dinosaurs and birds中间会造成句子歧义.

我觉得是比较级与最高级的区别，现在时和现在完成时的区别。

再问，谁能解答呢？

yet在这里应该做一个递进连词。
