To determine which constitutional article is not related to children, we can analyze each option:
- Article 23: Prohibits traffic in human beings and forced labor. While it applies to all, it provides significant protection for children against exploitation.
- Article 21-A: Provides for free and compulsory education for children aged 6 to 14 years. This directly pertains to children.
- Article 42: Relates to just and humane conditions of work and maternity relief, not specifically to children.
- Article 24: Prohibits employment of children in factories and other hazardous employment, directly relating to children.
Therefore, Article 42 is the article that is not specifically related to children.
