The part after the comma neither seems like a phrase nor a noun+noun modifier. It looks a full sentence and hence is run-on. INCORRECT

too wordy. Option A is pretty concise. INCORRECT

e) increasingly been treated with neglect
Same as D

To answer your question, D is just too wordy. Think of it this way - is the wordiness really required to give some extra valuable info ? Without the extra wordiness does the meaning change?

The answer to both questions is NO. The meaning for both Option A and D is the same.

Hence you can safely eliminate D.
