GMAT Sentence Correction (SC) | Re: When members of a group make it known

Hi,
IMHO,(E) is grammatically correct,but quite wordy.(D) is incorrect as the comma is missing before "nor".I am torn among (A),(B) and (C)

My question is how far ellipsis can go?
Can (A) and (B) read as below respectively?

they have neither prevented the artist from creating the art nor[they have neither prevented the artist] from displaying...

neither have they prevented the artist from creating the art nor[have they prevented the artist from] displaying...

Please help clarify
Thanks
