Final answer:
The correct answer is option d. In a traditional volleyball game, with strict adherence to professional rules, 12 players participate. However, in a physical education classroom setting, games can be adapted to include an entire class by modifying the rules to promote inclusion and activity.
Step-by-step explanation:
The number of people who can participate in a volleyball game is 12, with six players on each side of the net. However, in a physical education class setting, where participation and involvement are the main goals, the game can be adapted to include an entire class by rotating players in and out of the game, changing team sizes, or setting up multiple games if equipment and space permit.
The essence of the game in an educational setting shifts from strict adherence to professional rules to emphasizing inclusion, fun, and physical activity.
