The leader elected by the MLAs of the majority party or coalition
Explanation
According to Article 164 of the Constitution of India, the Chief Minister is appointed by the Governor. However, in a parliamentary system of government, the Governor acts in accordance with established conventions. The Governor appoints the leader of the party or coalition that commands a clear majority in the State Legislative Assembly as the Chief Minister.
Option Analysis
- The leader of the opposition party is incorrect: The leader of the opposition party is responsible for holding the government accountable and opposing its policies in the legislature. They do not form the government.
- The leader elected by the MLAs of the majority party or coalition is correct: Following the declaration of election results, the Members of the Legislative Assembly (MLAs) of the majority party (or pre-poll coalition) convene to elect their legislative party leader. The Governor then invites this elected leader to be sworn in as the Chief Minister.
- The candidate who secured the highest margin of victory in their constituency is incorrect: The margin of victory in an individual constituency reflects a candidate's local popularity but is not a constitutional criterion for appointment as Chief Minister.
- The senior-most member of the Legislative Assembly is incorrect: The senior-most member of the Legislative Assembly is traditionally appointed as the Speaker Pro Tem. Their primary role is to administer the oath to new members and oversee the election of the Speaker, not to head the government.
Key Takeaway: While Article 164 vests the power of appointment in the Governor, the constitutional convention mandates that the appointee must be the leader of the majority party or coalition in the Legislative Assembly.
