Which item is listed as an express enumerated power of Congress in the mnemonic?

• A. Postal
• B. Admirality
• C. Citizenship
• D. Armies

Answer: (A)

The express enumerated powers are the specific authorities listed for Congress in the Constitution, and a mnemonic is often used to jog memory of them. Establishing post offices and post roads is one of those explicit powers, so the mnemonic uses a cue that points to Postal. That makes Postal the best fit because it directly represents the power to create and run the postal system. The other options don’t match that particular mnemonic cue: Admiralty isn’t a listed mnemonic item for Congress’s express powers; Citizenship isn’t the mnemonic cue for naturalization (though naturalization is another enumerated power); Armies is an enumerated power as well, but the mnemonic in this context is centered on Postal.
