选C， make a synthetic .....  语义重复； 且D中的painstakingly意指的对象貌似是scientist，不合逻辑。

为啥就语义重复了呢？painstakingly如果修饰的对象不是scientist，那是什么呢？
个人选D，主动优于被动原则

ignore other problems, the meaning in D is wrong.

Before scientists learned how to make a synthetic growth hormone, removing it painstakingly in small amounts from the pituitary glands of human cadavers.

(C) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed---Here "it" means growth hormone.

(D) learning how to make a synthetic growth hormone, scientists had to remove it painstakingly--Here"it" means "a synthetic growth hormone"

Before the scientists have the ability to synthetic growth hormone.  remove what? the "synthetic growth hormone"? WRONG
it should be " growth hormone"

focu on the meaning of "it", sometimes it can change the original meaing of the sentence.
