我认为选B,都用被动的感觉更好。具体说为什么我也说不出来
具体例子见以下example:
The children pursue their study, undisturbed by the many visitor.

left......by human不是体现被动了么?

这是我一个local同学的回答:
B sounds like the correct one to me. I don't know the technical reason for it, but my feeling is that you should use past-tense for it, because it's talking about what will happen (reach a very old age) if something else _has happened_ (past tense).

Also, I don't think I've ever come across "undisturbing" as a word.

B虚拟语气吧,与过去相反,省略了一部分,if they were left undishturbed ……

选B 首先虚拟语气排除后两项, 被动语态排除第一项
变老是必修课,成熟则是选修课

A. left undisturbing
B.left undisturbed
C. le ...

I think it is a subjunctive sentence,too. From the latter part of the sentence, we can easily realize that it means "如果没有被人类打扰的话,它们会活很长时间"。这句话属于虚拟语句中从句的z主语和be动词(they were)省略。

选B,left表被动,undisturbed为形容词,表状态。
