The correct answer is (b), Presidential Government.
India has a parliamentary system of government, which means that the executive branch is responsible to the legislative branch. The President of India is the head of state, but the Prime Minister is the head of government. The Prime Minister is appointed by the President and must have the support of the majority of the members of the Lok Sabha, the lower house of the Parliament of India. The President can only dismiss the Prime Minister if the Prime Minister loses the confidence of the Lok Sabha.
A presidential system of government is one in which the executive branch is not responsible to the legislative branch. The President is elected by the people and is not accountable to the Parliament. The President has the power to appoint and dismiss the Prime Minister and other members of the government. The President can also veto laws passed by the Parliament.
The independence of the judiciary is a key feature of the Indian Constitution. The Supreme Court of India is the highest court in the country and has the power to strike down laws that it deems to be unconstitutional. The judges of the Supreme Court are appointed by the President on the advice of the Prime Minister and the Chief Justice of India. They hold office until they reach the age of 65.
A federal government is one in which power is shared between the central government and the state governments. The Indian Constitution provides for a federal system of government. The central government has power over matters such as defense, foreign affairs, and currency. The state governments have power over matters such as education, health, and law and order.
