Why is it better to adjust chair, table, and screen together?

Answer and explanation

Correct answer: Because full body posture is affected by them

The direct answer is A: the chair, table, and screen should be adjusted together because they jointly affect the whole body posture. Ergonomics means arranging work, furniture, and equipment so that a person can work safely, comfortably, and efficiently. First, the chair supports the body; then the table should allow relaxed arms; finally, the screen should be at a suitable height and distance so the neck does not bend. Changing only one item may leave another body part strained. Option A is correct because posture depends on the relationship among all three objects. Option B is wrong because colour does not explain posture or ergonomic benefit. Option C is wrong because adjustment does not directly increase salary. Option D is wrong because it has no logical connection with posture and holidays. Exam cue: treat a workstation as one connected system, not as separate objects.
