Which enumerated power relates to operating the national post office?

• A. Postal
• B. Arms
• C. DC and territories
• D. Copyright and patents

Answer: (A)

The key idea is the postal power—the Constitution gives Congress the explicit authority to establish post offices and post roads, creating and regulating a nationwide mail system. This power is specifically designated to Congress in Article I, Section 8, making it the clear basis for operating the national post office. It’s about a uniform, nationwide service, which requires federal authority across all states. The other options point to different areas of federal power—military funding, governance of federal districts and territories, and intellectual property rights—none of which authorize running the postal system.
