Answer:
The correct answer is option A.
Explanation:
Nominal GDP is the measure of economic growth which calculates the change in output on the basis of the current price. It is not inflation-adjusted measure and is affected by changes in the price level. Â
Real GDP on the other hand, measures the change in economic output on the basis of constant price. It is an inflation-adjusted measure to calculate economic growth. Â
That is why, real GDP is preferred, because nominal GDP may overestimate or underestimate the change in output.
