1. Article 1: Deals with the Name and territory of the Union- Correct. Article 1 states that India, that is Bharat, shall be a Union of States, and it specifies the territories of the States and Union territories.
2. Article 2: Deals with the renaming of States- Incorrect. Article 2 deals with the admission or establishment of new States, granting Parliament the power to admit new states into the Union of India.
3. Article 3: Deals with the formation of new States and alteration of areas, boundaries, or names of existing States- Correct. Article 3 provides the procedure for the formation of new states and the alteration of areas, boundaries, or names of existing states by the Parliament.
4. Article 4: Deals with laws made under Articles 2 and 3- Correct. Article 4 specifies that laws made under Articles 2 and 3 to admit new states or alter state boundaries are not considered amendments under Article 368.
Thus, pairs 1, 3, and 4 are correctly matched. Only pair 2 is incorrectly matched.
