The correct option is Union Government.
Explanation
The distribution of legislative powers between the Centre and the States is defined in the Seventh Schedule of the Indian Constitution. To address subjects not explicitly mentioned in the Union, State, or Concurrent Lists, the Constitution provides for "residuary powers."Constitutional Analysis
- Article 248: This article explicitly vests the exclusive power to make any law with respect to any matter not enumerated in the Concurrent List or State List in the Parliament (Union).
- Entry 97 of Union List: This entry in List I reinforces the provision by assigning "any other matter not enumerated in List II or List III including any tax not mentioned in either of those Lists" to the Union legislature.
- Comparison with Other Federations: This feature is borrowed from the Canadian Constitution, which vests residuary powers in the Centre. This contrasts with the American and Australian constitutions, where residuary powers are vested in the States.
- Role of Government vs. Parliament: While the option states "Union Government," in the context of legislative competence in a parliamentary system, this refers to the central level of the federation (Parliament) as opposed to the State Governments.
Key Takeaway
Residuary legislative power in India lies exclusively with the Union Parliament, ensuring the Centre's supremacy over new or unforeseen subjects (e.g., Cyber Laws, Space Technology).
