GMAT Sentence Correction (SC) | Re: After the Second World War, the city of Cologne

I stand for E.
My reasoning .

past perfect is wrong - eliminate C ,
Run on - eliminate A
After ";" There is no proper pronoun that can assure to whom the bild News company is referring to .
B is gone.
Now only D and E are left. In D to whom the build paper is referring to is not properly presented. Moreover, It is not parallel.

So E is answer.
