Answer:
C) long-run vertical aggregate supply curve.
Step-by-step explanation:
Downward and Upward sloping aggregate demand curves will show how the dropping or rising of price level will affect the quantity of output demanded.
While long-run and short-run aggregate supply curves show how the price level relates to the quantity of production of goods and services. In short-run upward-sloping aggregate supply curve it shows the belief that “the quantity supplied increases when the price rises”.
While the long-run vertical aggregate supply curve shows the beliefs of economists that in long-run is only the labor, capital and technology that can affect the quantity of final goods and services that one economy can produce.
