OA is C. But I chose D because "scientists" was correctly placed right after the modifier. It is perfectly describing "scientists", but something else must be wrong with D that we haven't realised yet.

I think D sounds good. :-D

a) scientists learned how to make a synthetic growth hormone, removing it painstakingly
: Unclear. Who remove it?

b) scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly.
: No conjunction between 2 sentences.

c) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed
: Same problem as B. No conjunction.

d) learning how to make a synthetic growth hormone, scientists had to remove it painstakingly

e) learning how to synthesize the growth hormone, it had to be painstakingly removed by scientists
: Wrong referent. "It" cant learn.

This sentence has past perfect tense issue:

a) scientists learned how to make a synthetic growth hormone, removing it painstakingly (“removing” is working as modifier buy required a verb - eliminate it)

b) scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly. (Sentence has past perfect issue – one needs to be in a simple past – eliminate it)

c) scientists learned how to synthesize the growth hormone, it had to be painstakingly removed (This is correctly defining the past perfect – hold it)

d) learning how to make a synthetic growth hormone , scientists had to remove it painstakingly (why learning – eliminate it)

e) learning how to synthesize the growth hormone, it had to be painstakingly removed by scientists (why learning – eliminate it)

Answer: C
