If a worker gets tired quickly though the work is not difficult, what should be checked ergonomically?

Correct answer: Posture height reach and environment

Ergonomics studies how work, tools, furniture, space, and the surrounding environment fit the worker. A person may become tired even when the task itself is not intellectually or physically difficult. Poor posture, an unsuitable working height, excessive reaching, awkward access, noise, heat, poor lighting, or limited space can all increase fatigue.

Option D is correct because it asks for a combined check of posture, height, reach, and environment. Salary, holidays, and wall colour alone do not explain the ergonomic fit of the task. The word “quickly” suggests that the arrangement of work should be examined rather than assuming that the worker is simply unwilling or that the task is difficult.
