According to the UN Convention of the rights of the child which of the following is not a right?

The correct choice is: Employment

The UN Convention on the Rights of the Child (1989) guarantees children rights such as health care and safe drinking water (Art. 24), an adequate standard of living (Art. 27) and education (Art. 28). Far from giving a right to employment, it protects children from economic exploitation and hazardous work (Art. 32).

Hence the answer is ‘Employment’.
