The most accurate response is:
Expansionary fiscal policy should be used during recessions to help build the economy and contractionary fiscal policy should be used when there is high inflation.
Expansionary fiscal policy aims to stimulate the economy during periods of recession or economic slowdown by increasing government spending and/or decreasing taxes, thereby boosting aggregate demand and reducing unemployment. In contrast, contractionary fiscal policy is employed to cool down an overheating economy characterized by high inflation, by decreasing government spending and/or increasing taxes to curb aggregate demand.
