For the original sentence 2 OG says The modifier illogically describes it. Shouldn't the same be applied to the sentence 1 (oa c) as well? Please elaborate.

Thank you

The first one has more of a meaning issue. before developing the hormone synthetically, Scientists had to remove it [the growth hormone] from pituitary glands.

All other options except option C distort the meaning. For example option A says -- scientist were removing sythetic hormone from the human body. that's illogical.

Both the sentences are not similar in structure.

In the first sentence the structure is before X learned to do Y, Y was done in another way. The first clause doesn't modify the second clause.

Whereas in the second sentence "Delighted by the reported earnings for the first quarter of the fiscal year" this is a introductory modifier of Subject X and it is almost always wrong to mention the subject with 'it' the first time.

If the first sentence had been this way

Before learning to synthesize growth hormones, it was done by removing ...

Then you can compare. Hope you get it. The subject (scientists) should be coming in the place of 'it'

The main point is the first sentence doesn't seem to be a modifier error but just a pronoun error and is different from second sentence.

I guess i went too bad in explaining. Hope this helps .
