关于in danger of 的用法

这个知识点也是来自本月JJ，我刚才google了一下，发现两种说法都有：

in danger of becoming extinction

in danger of extinction

请问牛牛，在GMAT中出现，哪个更好啊？

63. Health officials estimate that 35 million Africans are in
                danger of contracting trypanosomiasis, or "African sleeping sickness," a parasitic disease spread by the
            bites of tsetse flies.

(A)  are in danger of contracting

(B)  are in danger to contract

(C)  have a danger of contracting

(D)  are endangered by contraction

(E)   have a danger that they will contract

in danger of 更多的强调状态

至于这个问题

in danger of becoming extinction

in danger of extinction

还有具体问题具体分析，

是强调extinction 过程还是结果

自己顶一下，看有没有哪位帮忙解答一下，谢谢
