Answer:
a) true
Step-by-step explanation:
A rise in the general price level is called inflation and it affects the nominal value of the company's output. E.g. you sell pants and last year they sold at $10 and now since inflation rate is 10%, they sell at $11. But inflation only affects nominal values, it doesn't affect real values which are calculated using a base price of a certain year X, times the quantity sold. Following the example, your real output would not be $11 per pair of pants, instead it would still remain at $10 since the inflation is discounted.
