Why are sitting and standing postures studied in ergonomics?

Answer and explanation

Correct answer: To reduce body strain

The direct answer is A: postures are studied to reduce strain on the body. Ergonomics examines how the body sits, stands, reaches, lifts, and moves during work. A balanced posture keeps the head, spine, joints, and muscles in safer positions. This can reduce unnecessary pressure, tiredness, pain, and the risk of long-term musculoskeletal problems. Option A is correct because reducing body strain is a central purpose of ergonomic posture study. Option B is wrong because ergonomics aims to reduce avoidable fatigue, not create more of it. Option C is wrong because floor colour is unrelated to sitting or standing posture. Option D is wrong because the purpose is to make work safer and easier, not confusing. Exam cue: whenever posture is mentioned, connect it with comfort, health, and lower strain.
