Which of these is an example of a dual sport?

Badminton is categorized as a dual sport because it can be played in two main formats: singles (one player against one player) and doubles (two players against two players). This flexibility in the number of participants distinguishes it from the other choices listed, which are primarily team sports designed for larger groups of players.

In singles badminton, players engage in one-on-one competition, while doubles involves teamwork and strategy between partners. This duality in format allows for varied gameplay and skill development, which is a defining characteristic of dual sports. In contrast, soccer, basketball, and baseball typically involve larger teams and are primarily centered on team dynamics and coordination among multiple players.
