GMAT Sentence Correction (SC) | Re: The Book of Kells, an illumination of the four gospels

Can someone please explain, why (D) is not correct? It has is a slightly different meaning of a sentence, than in (E) (The book demonstrated pinnacle and incorporated pigments). In (D) I do see a parallel structure after "demonstrated": "...demonstrated (the pinnacle) AND (the incorporation)." The only possible wrong thing with (D) could be the wordiness in use of "incorporation" rather than verb "incorporate". Or that book can not demonstrate.
