Which statement about International Reply Coupon (IRC) is correct?

• A. It Requires a Special Stamp
• B. It Allows the Recipient to Pay for the Reply
• C. It Allows Senders to Prepay for a Reply
• D. It Is Used to Verify International Deliveries

Answer: (C)

The main idea here is that an International Reply Coupon lets the sender prepay the postage for a reply from the destination country. A sender buys the coupon from their postal service and includes it with the international mail. When the recipient in another country gets the item, they redeem the coupon in their own postal system to obtain postage to send a reply back to the sender. That prepayment by the sender is what makes this option work, so this statement is the best description.

The other options don’t fit because an IRC isn’t a special stamp attached to the letter, and the coupon is redeemed in the recipient’s country rather than altering the outbound postage. It also isn’t used to verify deliveries or to indicate who pays on the return; the purpose is specifically to prepay the return postage.
