According to Article 3 of the Constitution of India, the Parliament may by law : 1. declare war on any country 2. alter the boundaries of any State 3. increase the area of any State 4. establish an Autonomous Council within any State Select the correct answer using the code given below :

Article 3 of the Constitution of India empowers the Parliament to reorganize the internal map of the country. Specifically, it authorizes the Parliament to form new States, increase the area of any State, diminish the area of any State, and alter the boundaries or names of any State [2]. Statement 2 (alter boundaries) and Statement 3 (increase area) are explicitly mentioned under Article 3(d) and 3(b) respectively [2]. Statement 1 is incorrect as the power to declare war is an executive power of the President (subject to law) and falls under the Union's external affairs jurisdiction, not Article 3. Statement 4 is incorrect because Autonomous Councils are generally established under the Sixth Schedule (Article 244) or through specific state/central legislation, rather than Article 3. Thus, only statements 2 and 3 are correct according to the provisions of Article 3.
