What practical benefit is gained by understanding age and gender in work?

Correct answer: Work can be made safe fair and ability based

The direct answer is A: Work can be made safe, fair and ability based. Understanding age and gender helps us notice that workers may have different needs, risks and responsibilities. The reasoning is: first identify the worker's age and situation; then provide suitable duties, safety measures, hours and support; finally judge performance by ability rather than stereotypes. This creates inclusion and workplace justice. Option A is correct because it combines safety, fairness and ability-based work. Option B is wrong because understanding differences should reduce discrimination, not increase it. Option C is wrong because children need protection and education, not extra labour. Option D is wrong because removing equal opportunities is unfair and excludes capable people. A useful exam cue is: knowledge of age and gender should improve protection, equality and suitability of work.
