GWD一道比较题求助

Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal's than a cold-blooded reptile's.

A. that many species of dinosaur had a metabolism more like

B. that the metabolism of many dinosaur species were more like

C. that the metabolisms of many species of dinosaurs were more like those of

D.there were many species of dinosaurs that had metabolisms more like those of

E.there were many dinosaur species that had a metabolism more like that of

答案 给的是A， 为什么不选C呢？ 请大家指点一下

同意楼上。补充一点。BC选项将the metabolism 提到many dinosaur species之前，改变了原句的重心，也是错误的。DE选项作为主句的定语从句，前面没有加连词that。

A. that many species of dinosaur had a metabolism more like

但是怎么总觉得A中 many species of dinosaur had a metabolism 与 a warm-blooded mammal's 不平行啊，请问我应该怎么看这个句子呢。多谢了！

DE是宾语从句吧。。。

如果用了those of的话第二个比较就不平行了

是宾语从句，打错了，抱歉
