The Right to Education Act (RTE) in India guarantees free and compulsory education to children between the ages of:

3-14 years
6-14 years
6-18 years
5-16 years

The correct answer is: b) 6-14 years.

The Right of Children to Free and Compulsory Education Act, 2009 (RTE Act) is an Act of the Parliament of India enacted to provide free and compulsory education to all children aged 6 to 14 years. The Act was passed on 4 August 2009 and came into force on 1 April 2010.

The Act makes it mandatory for all children in the age group of 6 to 14 years to be enrolled in school and receive free education. The Act also provides for the establishment of a National and State Councils for Elementary Education to oversee the implementation of the Act.

The Act has been hailed as a landmark legislation that will go a long way in ensuring that all children in India have access to quality education. However, the Act has also been criticized for its lack of implementation and for the poor quality of education that is being provided in many schools.

The Act has been amended twice, in 2012 and 2017. The 2012 amendment introduced a provision for the appointment of special officers to oversee the implementation of the Act. The 2017 amendment introduced a provision for the establishment of a National Commission for Protection of Child Rights (NCPCR) to protect the rights of children.

The RTE Act is a significant piece of legislation that has the potential to transform the lives of millions of children in India. However, the Act needs to be implemented effectively in order to achieve its full potential.

The other options are incorrect because they do not fall within the age group of 6 to 14 years.
