Explanation
Why Correct: Article 51A of the Indian Constitution currently lists 11 Fundamental Duties. The original 10 duties were added by the 42nd Amendment (1976), and an 11th duty (to provide education to children aged 6-14) was added by the 86th Amendment (2002).
Distractor Analysis: Five does not correspond to any count in the Constitution; the original Fundamental Rights were seven, not five. Seven is the original number of Fundamental Rights (before the 44th Amendment), not duties. Ten was the original number of Fundamental Duties after the 42nd Amendment but before the 86th Amendment.
Takeaway: Remember: 11 Fundamental Duties under Article 51A. The 42nd Amendment added 10 duties; the 86th Amendment added the 11th. Examiners often test the difference between the original 10 and current 11.
