Answer & solution
Answer: (d) Right to Property
Answer: Option 4 — Right to Property
The Right to Property is not part of Article 21. The 44th Amendment (1978) removed it from the Fundamental Rights; it is now a constitutional legal right under Article 300A.
Free legal aid, privacy and livelihood have all been read into Article 21 by the Supreme Court.
Revision note — Article 21 (Protection of life and personal liberty)
• Text: no person shall be deprived of life or personal liberty except according to procedure established by law (idea borrowed from Japan).
• Available to all persons — citizens and foreigners.
• Maneka Gandhi case (1978) widened it: the procedure must be fair, just and reasonable.
• Rights read into Article 21: privacy (K.S. Puttaswamy, 2017), livelihood (Olga Tellis, 1985), free legal aid (Hussainara Khatoon, 1979).
• Others read in: clean environment, speedy trial, shelter, health, dignity.
• Article 21A — free and compulsory education for 6–14 years, added by the 86th Amendment (2002).
• Articles 20 and 21 cannot be suspended even during a National Emergency (44th Amendment).
