The correct answer is Canada, USA, and Mexico.

The 23rd FIFA World Cup, held in 2026, will be a joint venture between these three North American nations. This decision was made by FIFA, the international governing body for football, after a competitive bidding process. The tournament will be unique in its tri-national hosting, aiming to leverage the extensive sporting infrastructure and passionate fan bases across the three countries. This collaborative approach marks a significant shift in the hosting model of the World Cup, representing a larger scale and wider geographical spread than previous tournaments. The allocation of matches between the three nations will be determined based on factors such as stadium capacity and logistical considerations, ensuring a smooth and efficient operation of the event.

Options 1, 2, and 4 are incorrect. France, Germany, Italy, Spain, Poland, and Austria were not selected as joint hosts for the 2026 FIFA World Cup.
