Which of the following topics can be associated with ergonomics?

• A. Optimal productivity
• B. Safety and efficiency
• C. Work-related risks and injuries
• D. All of the above

Answer: (D)

Ergonomics focuses on designing work to fit people so they can perform tasks safely, comfortably, and effectively. When workstations, tools, and processes are aligned with human abilities, safety improves and tasks can be completed more efficiently, boosting productivity. At the same time, ergonomics targets reducing risks and injuries by addressing posture, repetitive motions, force, and cognitive load. Because it covers improving productivity, enhancing safety and efficiency, and lowering work-related risks and injuries, ergonomics is associated with all of the above.
