Explanations:The President of India is the head of state and holds a significant constitutional role. The President is elected by an electoral college consisting of elected members of both houses of Parliament and the legislative assemblies of the states. The President is the nominal head of the executive, legislative, and judiciary branches of the government. However, the President's powers are largely ceremonial and are exercised on the advice of the Council of Ministers headed by the Prime Minister.

The Prime Minister is appointed by the President and is usually the leader of the political party or coalition that has a majority in the Lok Sabha (the lower house of Parliament). The Prime Minister is responsible for the day-to-day administration of the government and is the principal advisor to the President on all matters of governance.
