The correct answer is option 2 - 14 years. The Constitution of India recognizes education as a fundamental right for children. According to Article 21A, the State shall provide free and compulsory education to all children aged between 6 and 14 years. This means that every child in India, within this age group, has the right to receive quality education at no cost. It is important to note that the Constitution mandates both free and compulsory education, meaning not only is education provided without any financial burden, but it is also obligatory for children in this age group to attend school. This provision aims to ensure that every child in India has access to basic education and promotes universal literacy.
