Which organization was formed to unite different national disability sports federations?

The International Paralympic Committee (IPC) is the correct answer because it was specifically established to serve as the governing body for the Paralympic Movement. The IPC's primary mission is to promote and support the development of sports for athletes with disabilities across various nations. By uniting different national disability sports federations, the IPC fosters collaboration and ensures a coherent approach to the organization of international competitions, including the Paralympic Games.

The IPC provides resources, guidance, and a framework for these national federations, ensuring they operate under the same principles and standards. This unification is essential for elevating the profiles of adaptive sports globally and enhancing the opportunities for athletes with disabilities to compete at various levels.

Other organizations mentioned, such as the National Paralympic Association and the International Olympic Committee, play different roles within the sports ecosystem. The National Paralympic Association pertains to each country’s own structure and support for Paralympic sports, while the International Olympic Committee primarily focuses on the Olympics and does not specifically cater to the needs of disability sports on its own. Additionally, phrases like "Global Sports Federation" do not define an established organization recognized for unifying national disability sports federations.
