Correct Answer:
B. To conduct elections
The correct answer is To conduct elections. The Election Commission is an independent constitutional body established with the primary and fundamental purpose of organizing, holding, and supervising free, fair, and transparent elections. This ensures the democratic process functions effectively and impartially.
The other options describe functions typically assigned to different branches or bodies of government. To appoint judges is a role of the judiciary or executive, often involving a judicial commission. To interpret laws is the exclusive domain of the judiciary. To advise the President is a broad function that may be performed by various governmental bodies, but it is not the core constitutional mandate of an Election Commission.
