请大家帮忙解一道题，谢了！

Researchers have discovered a new poison, bromethalin, that is lethal to all rats, even to those species that have become immune to other poisons, as well as to those rats that eat only the most minute quantities. Tests have demonstrated that rats will not learn to avoid bromethalin and that carcasses of rats killed by bromethalin pose no threat to the well-being of other animals.

which of the following statements, if true, would support the researchers' claim that carcasses of rats killed by bromethalin will not pose a threat to other animals?

A) Rats that consume bromethalin die immediately.

B) Animals, promopted by curioity, often examine carcasses that appear in their territory.

C) Chemicals in the digestive tract of dead rats quickly break bromethalin down into a nontoxic substance.

D) Traces of bromethalin remain in the rat's mouth and saliva after the rat eats the poison.

E) Certain animals are scavengers and feed habitually on refuse and dead flesh.

正确答案是C）

我选了B），其它动物由于好奇，经常会查看出现在它们领地内的尸体，我觉得因为动物会查看尸体，才因此不会吃被bromethalin毒死的老鼠，bromethalin对这些动物才不会有危险。为什么不对呢?

why u judged other animals won't eat the body after an examination driven by curioity?

有的时候想得太多了，我觉得这个选项和题目无关的。
