01 How does Rajya Sabha strengthen the federal structure?
Answer and explanation
Correct answer: A. It gives states a role in national law-making
Explanation: Federalism requires the Union and the states to participate in governing the country. Rajya Sabha represents the states and union territories at the national level, so their perspectives can enter parliamentary debates and legislation. Its members are not simply members of Lok Sabha, and it does not abolish state legislatures or control the judiciary. Thus option A correctly explains how the Council of States supports federal participation.
