Explanation
Why Correct: Articles 20 and 21 remain enforceable during a National Emergency because Article 359 explicitly bars their suspension. The 44th Amendment Act, 1978, added this protection.
Distractor Analysis: Articles 19 and 32 can be suspended during a National Emergency under Article 359; Article 19 protects freedom of speech, assembly, movement, etc., and Article 32 guarantees the right to move the Supreme Court for enforcement of Fundamental Rights. Articles 14 and 15 are also suspendable; Article 14 guarantees equality before law, and Article 15 prohibits discrimination on grounds of religion, race, caste, sex, or place of birth. The option "All are right" is incorrect because only Articles 20 and 21 are exempt from suspension.
Takeaway: The 44th Amendment Act, 1978, also restored the right to property as a legal right under Article 300A, removing it from the list of Fundamental Rights.
