The right to free and compulsory education for children between 6 and 14 years was made a Fundamental Right by the 86th Constitutional Amendment Act, 2002.
This amendment inserted a new article, Article 21-A, into the Constitution.
Prior to this, the Supreme Court of India in the Unni Krishnan case (1993) had held that the Right to Education is a fundamental right that flows from the Right to Life under Article 21.
The court interpreted Article 21 (Right to Life and Personal Liberty) to be broad and to include the right to live with human dignity, which in turn includes the right to education.
Although now an explicit right under Article 21-A, it is fundamentally derived from and considered an integral part of the Right to Life (Article 21). Among the given options, 'Right to Life' is the most appropriate foundational right.
