Answer:
C. A Tax Cut
Step-by-step explanation:
Discretionary Fiscal Policies are deliberate corrective policies taken by government to correct deviation (under / above production) from full employment level .
In case of recession i.e production below full employment level , policy makers will follow ' Expansionary Fiscal Policies ' i.e will reduce taxes & increase government spending (general - on national parks is irrelevant) .
Technically : AD = C + I + G + NX , where increase in 'G' will increase Aggregate Demand and help getting economy out of recession forces .
