The Environmental Protection Agency frequently puts mandatory controls on toxic substances that present as little risk as one in a million chances to cause cancer.

(A) as little risk as one in a million chances to cause

(B) as little risk as one chance in a million of causing

(C) as little risk as one chance in a million that it will cause

(D) a risk as little as one chance in a million for causing--> a risk as little as one chance in a million of casuing

(E) a risk as little as one chance in a million for it to cause
正确答案为E。
疑惑的是比较结构。如果把D答案改为a risk as little as one chance in a million of casuing 可以作为正确选项吗？
就是说present as little as risk as one chance in a million 与present a risk as little as one chance in a million 有区别吗？

D 即使改了我觉着也不对，除非变成 a risk as little as one in a million只有这样才能使得后面的成分于little可比较，楼主觉着叻？
