I have a small concern for choice D has redundant "previously", past perfect already implies -> previously.

But for this, choice D looks perfect.

can any one please help?

(A) being one of the most significant developments of the nineteenth century, had turned cotton cloth into an affordable commodity; it was costly before that

(B) having been one of the most significant developments of the nineteenth century, turned cotton cloth into an affordable commodity, costly previously

(C) one of the most significant developments of the nineteenth century, turned cotton cloth into an affordable, however costly previously, commodity

(D) one of the most significant developments of the nineteenth century, turned cotton cloth into an affordable commodity, whereas it had previously been costly

(E) being one of the most significant developments of the nineteenth century, turned cotton cloth from a previously costly commodity to an affordable one

Guys, need some help here. I've read through all comments on this questions in all forums but still can not understand why D is the right answer.

(D) one of the most significant developments of the nineteenth century, turned cotton cloth into an affordable commodity, whereas it had previously been costly

Why is "it" unambiguous in this question? I feel it can refer to cotton, commodity, or even invention of cotton gin. It's clearly not clear to me what "it" refers to...

Anyone can help me?
