Answer is D IMO. In C, scientist should be plural. In E, 'it have' is not correct.
OA?

I pick C. For D, the sentence implies that scientists extracted synthetic growth hormone, not naturally occurring growth hormone, from human bodies. This, I think, changes the meaning. The only thing strange about C is the word "the" preceding "growth hormone." I suppose that if the sentence is referring to a specific growth hormone, then it's okay. But isn't "scientists" plural in C? Maybe it was edited later.

you are correct , synthetic can not be used as something synthetic can not be extracted from humans also , after reading question , i understand that E is wrong because E uses have instead of had OA:C

Now C makes sense.

I agree with 'C'.
A,B and D are out for redundancy. E has messed up tenses.

IMO C
A,B,D can be ruled out because it uses the term "A synthetic growth hormone " and uses "it " later on , implying that the synthetic growth hormone had to be extracted , which makes no sense .
E - The tense is wrong .
Only C brings out the meaning clearly

E. Learning how to synthesize the growth hormone, it have to be painstakingly removed by scientists
Between C and E - which one is correct , please provide proper explanation IMO D. Present participle modifier issue here. D correctly addresses is it by placing "scientists" at the beginning of 2nd clause. C- no clear referent for pronoun "it" B- learned about making is awkward. A- no clear referent for pronoun "it"

A- no clear referent for pronoun "it" I went through the answers and realized my above post is wrong. D is obviously incorrect because of meanining issues. C wins.
