GWD4的语法题 急 马上就考试了,哪位路过的大侠帮帮忙吧

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

想不通为什么是这样的, 主谓都不知道是什么 如果选A. 而且读的非常不顺口.

A中的主语是fossils，谓语是offer，全句是fossils offer the most dramatic evidence (yet discovered) of the close evolutionary relationship.        yet discovered是修饰evidence，D中时态有问题，且丢失了原句部分含义

谢谢 明白了 之前还觉得YET比较奇怪.

那想多问句 b的语法没错吧？ 是不是因为把原句的意思改掉了 所以不选？

没人回答阿。。。个么顶下先。。
