再问：gwd-21-39，关于like比较前后的单复数

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

1. the cheetah species’ homogeneity makes them especially vulnerable to disease
           
2. the cheetah species is especially vulnerable to disease because of its homogeneity
           
3. the homogeneity of the cheetah species makes it especially vulnerable to disease
           
4. homogeneity makes members of the cheetah species especially vulnerable to disease
           
5. members of the cheetah species are especially vulnerable to disease because of their homogeneity

答案E，没意见。。。看到有人说排除B是因为like后面是复数，所以后面主句主语也要是复数名词。
有这种说法么？like前后不是只要同类可比事物就可以了么？难道连单复数也要一致？那如果一个人和一群人比呢？

请问D错什么地方了？
