Less than 35 years after the release of African honeybees outside Sao Paulo, Brazil, their descendants, popularly known as killer bees, had migrated as far north as southern Texas.

(A) Less than 35 years after the release of African honeybees outside Sao Paulo, Brazil,

(B) In less than 35 years since releasing African honeybees outside Sao Paulo, Brazil,

(C) In less than the 35 years since African honeybees had been released outside Sao Paulo, Brazil,

(D) It took less than 35 years from the release of African honeybees outside Sao Paulo, Brazil, when

(E) It took less than the 35 years after the time that African honeybees were released outside Sao Paulo, Brazil, and then

请问这道题为什么选A?
"the 35 years...."这种表达方式肯定不对，所以我排除了C和E。但是B和D到底错在哪里？那个when错了吗？语法笔记说的太绕了，而且这题的笔记我觉得很牵强。请各位指教！谢谢。

还请大牛继续说说那个in less than 35years 对不对啊？
个人观点，欢迎指正

那么答案是怎么说的呀？他们的后代把他们的祖先给解放了？？？他们的祖先解放的时候，descendants还没出生呢。。。。
好像是这样的：当honeybee被解放了，他们的后代才能migrate
