Recently discovered fossil remains strongly suggest that the Australian egg-laying mammals of today are a branch of the main stem of mammalian evolution rather than developing independently from a common ancestor of mammals more than 220 million years ago.

B. rather than a type that developed independently from

C. rather than a type whose development was independent of

答案是b

为什么不能选c？因为有歧义吗？

谢谢：）

意思不一样，independent from翻译过来是‘从。。。独立发展过来’

indendent of翻译过来是‘和。。。比是独立的’

They both have the same meaning, only that in the context of the question, B excels in the way of structure.

C被动不大好吧

B主动好一些

NN指教

C不是被动语态。

新东方老师总结的是：动词〉抽象名词，所以developed>development,我用这条排除的c.

我还觉得independent of不对？（不知道是不是）

请指教。
