When the economy is in a short-run equilibrium, with output greater than potential GDP, the short-run aggregate supply curve will shift to the left. Why would this happen?

a- With output above potential GDP, the economy produces too many goods and those goods are sold at prices that are too high.

b- This happens only after government interference.

c- With output above potential GDP, wages will be bid up and the expected price level will rise from the increase in the actual price level.

d- With output above potential GDP, the economy does not produce enough goods and those goods are sold at prices that are too high.
