The correct option is Impeachment of the Prime Minister.
Explanation
In a Parliamentary system of government, the Executive is accountable to the Legislature. The Constitution of India and the Rules of Procedure of Parliament provide specific mechanisms and procedural devices to ensure this accountability and control.Option Analysis
- Impeachment of the Prime Minister: Incorrect Mechanism. The term "Impeachment" is constitutionally reserved for the removal of the President (Article 61) for violation of the Constitution. The Prime Minister is not impeached; they hold office during the pleasure of the President, which is contingent upon enjoying the confidence of the Lok Sabha. If the Prime Minister loses this confidence, they must resign or be dismissed.
- Vote of no confidence: Correct Mechanism. The Council of Ministers is collectively responsible to the Lok Sabha under Article 75(3). A Vote of No Confidence is a direct parliamentary device to test this majority. If passed, the government must resign.
- Questioning ministers: Correct Mechanism. Questioning ministers (during Question Hour and Zero Hour) is a primary tool for parliamentary oversight. It allows members to elicit information on public importance and hold the government accountable for its administrative acts and omissions.
- Financial control: Correct Mechanism. Parliament exercises Financial Control over the Executive through the authorization of the Budget (Article 112), voting on Demands for Grants, and the scrutiny provided by Financial Committees (such as the Public Accounts Committee). The Executive cannot spend public money without Parliamentary approval.
Key Takeaway
Parliamentary control over the Executive is exercised through devices like the No Confidence Motion, Question Hour, and Financial oversight. Impeachment is a quasi-judicial process applicable to the President and Judges, not the Prime Minister.
