Correct answer: B. Six to fourteen years
Explanation: The direct answer is B, six to fourteen years. Article 21A places free and compulsory education for children aged six to fourteen within Fundamental Rights. To solve it, first notice the phrase “Fundamental Right,” then recall the fixed constitutional age group, and finally match it with the option. Option A, three to six years, is not the Article 21A range. Option B is correct because it gives the exact constitutional group. Option C, fifteen to eighteen years, begins after the specified range and is therefore not the answer to this question. Option D, eighteen to twenty-five years, concerns adults and is far outside the provision. This right means the State must provide access to elementary education without charging the child fees in the relevant public framework and must ensure compulsory access, subject to the law and educational rules. Do not confuse this age group with preschool education or later secondary education. Memory cue: Fundamental Right to Education = Article 21A = ages 6–14.
