Who is responsible for governing wheelchair rugby?

The governing body responsible for wheelchair rugby is the International Paralympic Committee (IPC). This organization oversees the development, promotion, and organization of Paralympic sports, ensuring that they are accessible and regulated correctly at both national and international levels. The IPC's involvement includes setting the rules and standards for competitions, facilitating international competitions, and ensuring fair play among athletes with disabilities. This governance is crucial for maintaining the integrity and growth of wheelchair rugby as a competitive sport within the Paralympic movement.

The other organizations listed, like the World Rugby Association and the National Rugby League, focus primarily on able-bodied rugby. The World Flying Disc Federation, which governs sports played with flying discs, such as ultimate frisbee, is unrelated to rugby, whether able-bodied or adapted for athletes with disabilities. Therefore, the comprehensive role of the International Paralympic Committee in managing wheelchair rugby makes it the correct answer.
