我非常唔明白點解係d!
nominal nation increased 10%, real national income increased 20%
即係real 大過nominal
即係有inflation出現..

As we all know that if price level rises, then the real national income would fall as purchasing power of dollar drops. Conversely, if price level falls, then the real national income would rise as purchasing power of money rises. In this question, % of real national income increases more than % of nominal national income, this is only possible that price level DROPS. Hence, the answer should be d).
