B). Are changes in taxes or government spending that increase aggregate demand without requiring policy makers to act when the economy goes into recession.

Explanation:

Automatic stabilizers are described as the kind of fiscal policy that particularly involves regulating income tax and government spending that assist in offsetting the fluctuations occurring in the economy automatically without any additional governmental operation or action.
