Okay so I looked at the question. If it were me, I would of, in this case, adjusted the real WACC using .101* 1.0078 to get a nominal WACC of 10.178%. It does say everything is nominal so we should be using a nominal discount rate as you said. In either case the answer is B because it does not even come close to the other two options. I am assuming the answer is B. I did not submit my answer for only question to verify.
