请教一道GMATPrep的语法题，以前没有讨论，谢谢

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

A.that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved

B.that has suggested the elephant descended from an aquatic animal, its trunk originally evolving

C.suggesting that the elephant has descended from an aquatic animal with its trunk originally evolving

D.to suggest that the elephant has descended from an aquatic animal and its trunk originally evolved

E.to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

答案是E，偶觉得E中的那个and that虽然是很平行，但系意思上很怪啊，另外，itr trunk的逻辑主语不是会有歧义吗？！谢谢！！

欧觉得没有歧义阿

这个选项最好的了

帮lz订！！！请问C为什么不对。。。
