Correct Option
The correct option is Only three pairs.
Explanation
Amendment procedures under the Constitution vary according to the subject matter and the degree of federal impact involved.
Certain constitutional changes are made by a simple majority in Parliament and are not treated as amendments under Article 368, while changes affecting federal provisions require both a special majority in Parliament and ratification by at least half of the states.
- Pair A: Correct. Admission or establishment of new states under Article 2 is done by a simple majority in Parliament and does not require the special procedure under Article 368.
- Pair B: Correct. Fundamental Rights can be amended by a special majority in Parliament under Article 368, subject to the basic structure doctrine.
- Pair C: Correct. Distribution of legislative powers between the Union and the states affects the federal structure and requires a special majority in Parliament plus ratification by at least half of the states.
- Pair D: Incorrect. Altering state boundaries under Article 3 requires a simple majority in Parliament, not a special majority.
Therefore, three pairs are correctly matched.
Key Takeaway: Changes affecting federal provisions require state ratification, while admission of new states and alteration of state boundaries are done by simple majority in Parliament.
