What is written at the bottom of an international article?

The correct choice highlights that the country name at the bottom of an international article is written in all capital letters. This convention is a standard practice in international mailing to ensure clarity and consistency when the item is processed and delivered across international borders. Using uppercase letters helps to enhance visibility and minimizes the potential for confusion regarding the country of origin, which can be particularly important in postal systems that handle numerous shipments from various countries.

This practice is necessary because international mail must navigate different postal rules and systems, and clear labeling plays a critical role in ensuring that mail is accurately routed and delivered. Standardizing the format by using capital letters aids postal workers in quickly identifying the country associated with the shipment. It reflects the universally accepted norms for international mailing, facilitating smoother processing at all points of handling.

While the other options might represent important elements of an international mailing, such as the sender's country, recipient's address, or shipping date, they do not address the specific requirement for how the country name must be presented on the item itself. The emphasis on using all capital letters is what makes this choice the correct answer.
