Which behavior is most likely to undermine efficiency in a team setting?

• A. Collaboration on complex tasks
• B. Regular breaks
• C. Active horseplay
• D. Clear communication

Answer: (C)

Active horseplay undermines efficiency because it creates distractions, interrupts focus, and can lead to mistakes or safety incidents. When teammates spend time dealing with interruptions or preventing disruption, less time and energy is available for productive work. In contrast, collaboration on complex tasks leverages diverse skills to solve problems faster, regular breaks help sustain energy and prevent burnout, and clear communication keeps everyone aligned and reduces rework. So the behavior that most reduces efficiency in a team is active horseplay.
