Which of the following is a requirement for the Entry Form?

The requirement that the Entry Form must be duly completed is essential because it ensures that all necessary information is provided for processing. A duly completed form means that all sections are filled out accurately and comprehensively, which is critical for verifying the player's eligibility, registration details, and adherence to FIBA regulations. This completeness is fundamental for the smooth functioning of the tournament and helps avoid any delays or miscommunication.

While submission methods and additional content like photos can be important, they don't affect the core requirement of having a fully completed form. In contrast, handwritten entries or specific submission formats may not align with the current technological standards and practices within FIBA, making the completion of the form the most vital aspect to focus on.
