Answer:
The correct answer is option B.
Step-by-step explanation:
Real GDP is the inflation-adjusted measure of economic growth. It measures the change in output level at a constant price. It measures changes in economic output.
Nominal GDP measures change in output level based on current prices. It is not an inflation-adjusted measure of economic growth.
Real GDP changes with a change in output level. While nominal GDP can change with change in either output level or price. So it is not necessary that a decline in real GDP is accompanied by a decline in nominal GDP.
