Which option is not exploitation?

Correct answer: Legal work with wages and consent

The direct answer is D: legal work with wages and consent. Exploitation involves taking unfair advantage, especially through force, trafficking, or prohibited child labour. Lawful work freely accepted by a capable person, with agreed wages and legal conditions, is generally not exploitation. Step by step: ask whether the person agrees; ask whether payment is provided; check whether the work is lawful and whether special protections apply. Option A is exploitation because forced unpaid work is forced labour and denies fair payment. Option B is exploitation because trafficking treats people as objects for unlawful control or gain. Option C is exploitation and also prohibited because children must not be employed in dangerous prohibited work such as mines. Option D is the correct exception because it includes legality, consent, and wages. Memory cue: consent plus fair wages points away from exploitation, but child-safety laws still apply.
