What are the financial obligations of the requesting national member federation regarding travel?

The correct answer is that the requesting federation must assume the player's travel expenses. This is based on the standards and regulations set forth by basketball governing bodies, which often stipulate that when a national member federation requests a player for international duty, it is their responsibility to cover the associated travel costs. This ensures that players are available for their national teams without financial burden, thereby promoting fair play and allowing nations to field their best talent during competitions.

The other options do not align with the established responsibilities regarding travel expenses. This arrangement aims to encourage participation in international events without placing additional financial strain on the players or clubs. Taking into account these obligations creates a clearer understanding of the roles and responsibilities within international basketball frameworks, particularly in fostering cooperation between national federations and player engagements.
