Why is keeping an object too far while working not proper?

Correct answer: It may cause repeated stretching

Direct answer: Option A is correct. Keeping an object too far away while working may cause repeated stretching and unnecessary strain. Ergonomics aims to reduce awkward posture, excessive reaching, and repeated movements. If a worker must extend the arm or bend the trunk again and again to pick up a tool, the muscles of the shoulder, arm, back, or neck may become tired. A good arrangement keeps frequently used objects within easy and safe reach, while still leaving enough clear space for movement. Option A works because it describes the direct physical problem caused by excessive reach. Option B is wrong because moving an object does not make the room physically larger. Option C is wrong because work does not happen automatically; the worker still has to perform it. Option D is wrong because the distance of an object does not by itself reduce noise. The exact best reach depends on the task and the person, but repeated far reaching is generally less comfortable and less efficient. Memory cue: frequent tool use plus far reach equals repeated strain; keep common tools nearby.
