Why is the best ergonomic solution considered one that looks at both the person and the task?

Answer and explanation

Correct answer: Because ability limitation work demand and tools together create risk

Direct answer: Option A, because ability limitations, work demands and tools together create risk. Ergonomics does not blame only the worker. It studies the fit between a person and the task. Step by step: every person has abilities and limits; a job places demands such as force, speed, repetition, posture or attention; tools and equipment can make those demands easier or harder; when the demands exceed the person’s capacity or the tool is poorly designed, discomfort, error or injury risk increases. A sound solution may adjust the tool, task, pace, workspace or training while considering the worker. Option A correctly includes this interaction. Option B is wrong because the person alone is not necessarily the problem. Option C is wrong because task demands directly affect fatigue and risk. Option D is wrong because tools can be badly positioned, unsuitable or difficult to use. Memory cue: fit the person, task and tool together.
