请教大家一道怎么也想不明白的题目

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.


	as little risk as one in a million chances to cause

	as little risk as one chance in a million of causing

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

	a risk as little as one chance in a million for causing

	a risk as little as one chance in a million for it to cause 答案给的是B，没弄明白到底是什么跟什么比较呢？为什么不能是risk和one chance in a million的概率比较呢？

貌似one chance in a million 是一个固定搭配来着，和a chance in a million of doing sth是一样的

没人回答再顶上来一下，请教牛牛们，这道题到底是什么和什么在比较呢？为什么不能是风险和风险比较呢？

我不是很确定
但我认为这不是一个比较，应该是一个主谓结构的
谓语是present 宾语是 risk；risk的固定搭配是risk of doing
可能句子结构就是present risk of causing ancer as little as one chance in a million
as little as one chance in a million是来修饰risk发生的几率的
