Almost like clones in their similarity to one another, the cheetah species’ homogeneity makes them especially vulnerable to disease.

E is correct

A.      the cheetah species’ homogeneity makes them especially vulnerable to disease

B.       the cheetah species is especially vulnerable to disease because of its homogeneity

C.       the homogeneity of the cheetah species makes it especially vulnerable to disease

D.      homogeneity makes members of the cheetah species especially vulnerable to disease

E.       members of the cheetah species are especially vulnerable to disease because of their homogeneity

请好心人帮帮分析一下。

B,如果没搞清对比对象也可通过单数与单数平行，复数与复数平行这个原则，b中是一个单数感念，故不能和clones比较。。。。。
