Answer:
Correct option is C.
If the economy is at full capacity, then the AS curve will be vertical
Step-by-step explanation:
The long-run aggregate supply curve is perfectly vertical, which reflects economists' belief that the changes in aggregate demand only cause a temporary change in an economy's total output. For the short-run aggregate supply, the quantity supplied increases as the price rises.
The full capacity AS curve is a long-run AS curved and it is vertical as the potential output level is denoted by it with the fully employed resources.
