The 11th Fundamental Duty was added by which Constitutional Amendment Act?

Answer: 86th Constitutional Amendment Act, 2002

Explanation: The 86th Amendment (2002) inserted clause (k) in Article 51A of the Constitution, adding the 11th Fundamental Duty. This clause makes it a duty of every parent or guardian to provide opportunities for education to his child or ward between the ages of six and fourteen years. The same amendment also inserted Article 21A, giving the Right to Education the status of a fundamental right.

Why the other listed amendments are incorrect:

• The 42nd Amendment (1976) introduced the original set of Fundamental Duties (ten duties), but it did not add the 11th duty.

• The 84th Amendment (2001) did not add the 11th duty.

• The 98th Amendment (2012) is not related to adding the 11th Fundamental Duty.

Quick memory aid: 86th Amendment = 2002 = added the duty on parents/guardians to provide education to children aged 6–14 (clause (k) of Article 51A) and also created Article 21A (Right to Education).
