What must accompany a player's FIBA Identity Card for competitions?

A player's FIBA Identity Card is essential for participating in competitions as it serves as a verification of their identity and eligibility to compete under FIBA's rules. It is mandated that the personal FIBA Identity Card must be presented for each player to ensure that only registered and approved individuals can participate in the event. This procedure helps maintain the integrity of the competition by confirming the player's identity against FIBA's official records, thereby preventing issues such as eligibility disputes or fraudulent participation.

While the other options mention documents that could be relevant in different contexts, they do not fulfill the requirement to accompany the FIBA Identity Card specifically for the purpose of competition. In competitions, the primary focus is on ensuring that the identity of each player is verified through the FIBA Identity Card itself, thus making it the necessary accompaniment for player participation.
