Why is real gdp a more accurate measure of an economy's production than nominal gdp?

a. real gdp measures the value of the goods and services an economy produces, but nominal gdp measures the value of the goods and services an economy consumes.
b. real gdp is not influenced by price changes, but nominal gdp is.
c. real gdp includes the value of exports, but nominal gdp does not.

The correct answer is option B.

Explanation:

Nominal GDP measures economic growth at current prices. It measures the value of output produced on the basis of current prices. It is thus not an inflation measure of economic growth as it includes the change in the price level.  

Real GDP is an inflation-adjusted method to measure economic growth. It measures a change in economic output on the basis of constant. It is thus considered a more accurate measure of the economic growth of a nation as it is not influenced by changes in the price level.
