Final answer:
Horseshoes is incorrect because it is not a dual sport.
Step-by-step explanation:
The incorrect option among the given choices is Horseshoes. Although tennis, soccer, and badminton can all be played by two players, horseshoes is typically played as a single-player or team game with multiple players on each side.
Tennis and badminton are considered dual sports as they can be played by two individuals or teams of two, with each player on opposite sides of the net. Soccer, on the other hand, is a team sport that typically involves more players on each side.
