GMAT Sentence Correction (SC) | Re: The 151 member governments of the World Bank are expected to

I was confused between C and D and picked D which is wrong.

D uses a modifier - an obstacle to congressional passage within commas. This means that it is functioning as a non-essential modifier - the removal of which does not affect the meaning of the sentence.
But in this case 'this modifier' is clearly essential to the meaning of the sentence and hence will change the meaning of the sentence if removed.
Hence D is poor construction

C wins. It uses the idiomatic form 'cite as Y X'

Hope that
