Why is it good to keep the mouse near the body?
Answer and explanation
Correct answer: To reduce hand and shoulder stretching
Keeping a computer mouse close to the body allows the arm to remain near a comfortable position instead of being stretched forward or sideways. This can reduce unnecessary reaching and may lower strain on the shoulder, upper arm, wrist, and hand during repeated work. The exact position should still allow the elbow and wrist to remain relaxed.
Option A is correct because a suitable reach reduces hand and shoulder stretching. Hiding the mouse, switching off the screen, and increasing sound have no connection with its ergonomic placement. Ergonomics does not mean placing every tool at any distance; it means arranging tools and posture to support safety, comfort, efficiency, and reduced fatigue.
