(D) Dissimilar to human beings, wasting away when（B）

(E) Lacking similarity to human beings, who waste away when

i was undecisive between B and C, can somebody tell me what's wrong with C????

我们都知道，主句，when+从句

这里的话，human beings waste away, when they go without ...

而这里有who，是作为human beings 的定语从句，代进去，这里的整个human beings waste away, when they go without ...是要来修饰unlike that of human beings的。

而C选项，按照，主句，when+从句，根据就不符合这里的规则了！

懂了，many thanx
