大全8, ANS(C)的have been

大全8.

A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, believed to be the largest flying creature the world has ever seen.

(A) believed to be

(B) and that is believed to be

(C) and it is believed to have been

(D) which was, it is believed,（C）

(E) which is believed to be

想請問大家,正確答案中的have been是不是應該為has been呀?

我認為主詞"the Quetzalcoatlus" 表一種生物,應該是單數,而且代詞 it不是也單數嗎?那是不是應該用has been?

請NN幫忙一下...^_^

to 后边要用动词原形，所以不可能存在to has been 这种形式
