The correct answer is D. Sovereignty, Territorial integrity, Federal system, Judicial review, and Parliamentary form.
Article 368 of the Indian Constitution provides for the amendment of the Constitution. However, there are certain features of the Constitution that cannot be amended, even under Article 368. These
features are:- Sovereignty: India is a sovereign, socialist, secular, democratic republic. This means that India is a free and independent country, and its people have the right to choose their own government.
- Territorial integrity: The territory of India is one and indivisible. This means that no part of India can be separated from the rest of the country without the consent of the Indian people.
- Federal system: India is a federal country, which means that power is shared between the central government and the state governments.
- Parliamentary form of government: India has a parliamentary form of government, which means that the head of government is the Prime Minister, who is elected by the members of the Lok Sabha (the lower house of Parliament).
- Judicial review: The Supreme Court of India has the power to review the laws passed by Parliament and the state legislatures. This means that the Supreme Court can strike down laws that it deems to be unconstitutional.
The other options are incorrect because they do not include all of the features of the Constitution that cannot be amended. Option A does not include the feature of sovereignty. Option B does not include the feature of territorial integrity. Option C does not include the feature of federal system.
