Correct use of ergonomics can increase which result?

Correct answer: Safety and efficiency

Direct answer: D, safety and efficiency. Ergonomics arranges tools, furniture, posture and work methods so that the task fits the person. A good arrangement reduces unnecessary force, awkward movement, fatigue and mistakes. As a result, the person can work more safely and often complete the task more efficiently. Option A is wrong because correct ergonomics should reduce, not increase, fatigue and risk. Option B is wrong because disorder and pain are problems that ergonomic planning tries to prevent. Option C is wrong because ergonomics aims to improve security and reduce errors, not increase insecurity and mistakes. Option D is correct because it expresses the two major benefits together: protection from harm and better use of time and effort. Reasoning chain: suitable design leads to comfortable movement; comfortable movement lowers strain; lower strain supports safer and more efficient work. Memory cue: good ergonomics gives “less strain, more safety, better work.”
