Answer:
B) Reductions in federal tax rates on personal and corporate income.
Explanation:
A recession is when there's a persistent decline in the economy. It is when the GDP growth rate for two consecutive quarters are negative.
In a recession, government ought to increase its spending and reduce taxes in order to increase disposable income and stimulate demand. These are expansionary fiscal policies.
Postponement of a highway construction program and reductions in agricultural subsidies and veterans' benefits reduces government spending.
When the government has a surplus, it either increases taxes or reduces spending which aren't expansionary fiscal policy.
