What is the requirement for a player under sanction by FIBA regarding licensing with national member federations?

The requirement stated in the question reflects the discipline and regulatory measures enacted by FIBA to ensure compliance and fair play within the sport. When a player is under sanction, it indicates that they have violated FIBA rules or regulations, which often leads to restrictions on their eligibility to participate in official basketball activities.

In this case, the correct answer indicates that a sanctioned player can only be licensed with the national federation that was in place at the time of the sanction. This ensures that the terms of the sanction are upheld, preventing the player from escaping penalties by simply switching federations. This policy fosters accountability and maintains the integrity of the competitions governed by FIBA, as it effectively ties the player's status directly to the specific federation that is overseeing their case during the period of sanction.

Thus, by limiting the player's capacity to license with other federations, FIBA upholds its disciplinary framework and ensures that all players adhere to the same standards and consequences, regardless of their national affiliations.
