标题: OG中有一句话看不懂

大家好，OG，83题的原题我看了半天楞是不明白说的什么意思。

Any medical test will sometimes fail to detect

a condition when it is present and indicate that there is one when it is not.

(A) a condition when it is present and indicate that there is one

(B) when a condition is present and indicate that there is one

(C) a condition when it is present and indicate that it is present

(D) when a condition is present and indicate its
presence

(E) the presence of a condition when it is there and
indicate its presence

答案是C，但整个句子怎么翻译呢？希望高手给个指点，先谢拉。

任何一种医疗测试，有时候：当一种情况存在时，检测不到；当不存在时，显示存在。
