विधान (A): काही विशिष्ट परिस्थितीमध्ये, राज्य सूचीतील कोणत्याही विषयावर कायदा करण्याचा अधिकार घटनेने संसदेला दिला आहे.
कारण (R): राष्ट्रीय आणिबाणीच्या अंमलबजावणीच्या काळात संसद राज्य सूचीतील कोणत्याही विषयावर कायदा करू शकते.
पर्यायी उत्तरे :

The correct answer is Option B (Both A and R are true but R is not the correct explanation of A.).

Key Points:
• Parliamentary Legislation on State List Matters:
• Assertion (A) is True: Under extraordinary circumstances, Parliament acquires the power to legislate on matters enumerated in the State List (List II). These conditions include:
• 1. Rajya Sabha passing a resolution under Article 249.
• 2. During a National Emergency under Article 250.
• 3. When two or more states request Parliament by resolutions under Article 252.
• 4. To implement international treaties under Article 253.
• 5. During President's Rule under Article 356.
• Reason (R) is True: Under Article 250, during the operation of a Proclamation of Emergency (Article 352), Parliament has the power to make laws for the whole or any part of India on any State List matter.
• Explanation Linkage: Reason (R) is merely one of five distinct independent circumstances under which Parliament legislates on the State list. It illustrates one instance, but it is not the exhaustive reason or explanation behind the broader constitutional design of Assertion (A). Therefore, as per MPSC key, both are true, but R is not the correct explanation of A.
• Hence, Option (2) is correct.
• Key Takeaway: Parliament can legislate on the State List during National Emergency (Art 250), Rajya Sabha resolution (Art 249), or by state consent (Art 252).
