Sentence Correction (SC) | Re: Studying skeletons unearthed near Rome, DNA evidence was recovered by

Hi ExpertsGMATNinja GMATNinjaTwo

Can you please explain what is so awkward about (D)

(A) and (B) are clearly out since opening verb-ing modifier should modify scientists and not evidence.

(C) being is not used in passive continuous tense also I feel evidence from is incorrect. It should be evidence by studying ..

(D)they correctly refers to scientists and not skeletons , is the phrase - from it- wordier?

(E) I did not select this since was confused if recovered is verb or modifier? note
