Which example protects children's rights?

Correct answer: Sending a child to school and protecting from hazardous work

The direct answer is option C. Children’s rights are protected when they receive education, safety, care and opportunities for healthy development, and are kept away from hazardous exploitation. Sending a child to school supports development, while preventing dangerous work respects the child’s dignity and legal protection. Option A is wrong because sending a child to a mine exposes the child to dangerous labour. Option B is wrong because operating dangerous machinery can cause serious injury and is a form of hazardous child labour. Option C is correct because it combines education with protection from danger. Option D is wrong because making a child work all night harms health, rest, education and safety. The question is not saying that every kind of help or age-appropriate activity is illegal; it asks which example clearly protects children. The best answer therefore shows both a positive right and protection from exploitation. Memory cue: school plus safety means protection; mine, machines or night labour mean danger.
