Concept:
Education was originally a Directive Principle under Article 45. The Supreme Court later recognized education as part of the Right to Life under Article 21, leading to a constitutional amendment.
Step 1: Identify the amendment.
The 86th Constitutional Amendment Act, 2002, introduced major changes relating to education.
Step 2: Understand the provisions inserted.
• Article 21A was inserted, making free and compulsory education a Fundamental Right for children aged 6 to 14 years.
• Article 45 was modified.
• Article 51A(k) was inserted as a Fundamental Duty of parents and guardians.
Step 3: Compare with other amendments.
• 42nd Amendment: Added Fundamental Duties and amended the Preamble.
• 44th Amendment: Modified Emergency provisions.
• 73rd Amendment: Constitutionalized Panchayati Raj Institutions.
Hence, the Right to Education became a Fundamental Right through the 86th Constitutional Amendment Act.
Therefore, Option (D) is correct.
