Tennis is typically played on a court, which is a specially designed area with specific dimensions and surfaces for the game. A court provides the necessary infrastructure and features like net, lines, and proper playing surface for players to engage in a competitive match. While it is possible to play tennis on a beach or in a park, these locations may not have the appropriate setup or conditions for a proper game. Therefore, the correct answer is "court" as it is the most suitable and commonly used place for playing tennis.
