Authority for annual mandatory expenditures is found in permanent statutes.

• A. Direct (Mandatory) Spending
• B. Discretionary Spending
• C. Revenue
• D. Outlay

Answer: (A)

Mandatory spending is driven by laws that authorize programs and set entitlement rules, so the spending is required automatically each year based on those formulas. The authority for this spending comes from permanent statutes—laws that establish and fix the eligibility and benefit terms—rather than from annual appropriations. Discretionary spending, on the other hand, is funded through yearly appropriations acts and can be adjusted year to year. Revenue and outlays describe income and actual spending, respectively, but they aren’t the source of authority for mandatory spending. That's why Direct (Mandatory) Spending is the right understanding here.
