Answer: (c)

Explanation:
Statement 1 is correct; The four Grand Slam tennis tournaments-Australian Open, French Open, Wimbledon Championships, and US Open-are governed under the Grand Slam Board, which coordinates policies and commercial interests among the four tournaments.

Statement 2 is incorrect because entry into Grand Slams is not simply open to all players above a certain age. Participation depends on ATP/WTA rankings, qualifying rounds, and wild cards, and there is no universal rule such as a minimum age of 14 for direct entry.

Statement 3 is Incorrect because while wild cards are granted at the discretion of tournament organizers, there is no strict global cap or uniform limitation on the number a player may receive across all Grand Slams; rules vary by tournament and are not defined as a fixed restriction applicable to all players in the manner suggested.
