Solution:
Task: Who among the children answered correctly? The teacher asked for examples of children's rights.
Analysis of answers:
- Vitya said: the right to free education. This is one of the fundamental rights of a child, enshrined in the legislation of many countries.
- Masha said: the right to parents. This is an incorrect wording. It is correct to speak about the child's right to a family, to parental care, but not "the right to parents.".
- Nikita said: the right to pocket money. This is not a fundamental right of a child. While children may have the right to receive pocket money, it is not a legally recognized right in the same category as education or family care.
Therefore, Vitya provided the most accurate and legally recognized example of a child's right.
Answer: Vitya.
