(D) was anger about the issue, which was raised over and over, and preventing the wounds from earlier battles, still raw, to begin healing
(E) were anger about the issue, which was raised repeatedly, and preventing the raw wounds from earlier battles to begin to heal


The answer is B. Can someone help me to explain why are we using was instead of were here?
Option C seems good to me.

Thanks

This is an inverted subject-verb sentence. Reverse it:

"Anger was among the emotions on display..."

not, "Anger were among the emotions on display..."

As he says , it talks about anger....so was is correct

One more notable thing is that Among a group of things one thing is asked making it singular so correct starting word should be "was" not "were" making it 3-2 split and between the two B is better choice any day.
