The final authority to decide any questions involving a payment to be made by an agency is:

• A. Comptroller General
• B. Secretary of the Treasury
• C. Director of OMB
• D. President

Answer: (A)

The final authority to decide questions about a payment made by an agency rests with the Comptroller General, who heads the Government Accountability Office. This role provides an independent check on how public funds are used. When an agency questions a payment or needs a determination on whether a payment is properly authorized and within the law, the Comptroller General’s office issues binding rulings through GAO settlement of accounts. While the Treasury handles the actual disbursement and the President and OMB guide policy and budgeting, they do not have the final say on individual payments. GAO’s impartial rulings ensure payments are legal, proper, and within appropriations.
