把D填入，后半句为 indicate its presence when it is not, 不一致

能说说为什么c一致吗？我觉得也不太一致啊。。

a condition when it is present

it is present when it is not

c的it始终指代condition 不会造成误解

.Any medical test will sometimes fail to detect a condition when the condition(it) is present and indicate that the condition(it) is present

我怎么觉得d也没造成什么误解！？

大家都来看看，帮忙解释的详细一点，谢了！！！

老想不明白，急死我了！

多敲鍵盤...鍵盤會壞...j/k

Someone/something detects something.
B跟D都馬上可以cross out...."Any medical test will sometimes fail to detect when..."
句子表達有問題, 根本不知道fail to detect what?
