Which of the following statements with regard to the Grand Slam Tennis Tournaments is/are correct?

1. The tournaments have a shared governance structure establishing the partnership among the four Grand Slam tournaments.

2. They are open for entry to all internationally ranked tennis players above the age of 14.

3. There is a limitation on the number of 'Wild Cards' a player may receive to compete in a Grand Slam Tournament.

Statement 1 is correct: The four major tennis tournaments (Australian Open, French Open, Wimbledon, and US Open) operate under a unified, shared governance structure facilitated by the Grand Slam Board (formerly the Grand Slam Committee). This board consists of representatives from the four tournaments and the International Tennis Federation (ITF) to ensure uniform rules and partnership code-of-conduct enforcement across all majors. Statement 2 is incorrect: While the rules prevent players under the age of 14 from competing, being "above the age of 14" does not automatically open entry to all internationally ranked players. To enter the Grand Slam qualification or main draws, players must meet strict performance-based ranking thresholds (typically a ranking of 500 or better) and adhere to structural age-eligibility phase-ins (such as the WTA/ATP Age Eligibility rules that restrict workload for players aged 14–17). Statement 3 is incorrect: According to the official Grand Slam Rulebook, there is no limitation on the collective number of wild cards a player may receive to compete in Grand Slam Tournaments. While regular ATP and WTA tour events place strict limits on annual wild cards to protect competitive integrity, each Grand Slam tournament committee retains absolute independent discretion over its entry invitations.
