The correct answer is the British Parliament.The Parliament of IndiaOn the basis of the relationship between the executives and the legislature, two major systems of democratic government have been developed - The Parliamentary System and the Presidential System. India has adopted the parliamentary form of government in the line with the British Westminster model.The Parliamentary system is also known as the cabinet system Responsible government or Prime Minister Model. The Parliament of India is primarily based on the model of the British Parliament. Hence, Option 2 is correct.A parliamentary system is a form of government where executives hold the power with the majority support of the legislature (usually the people's elected house).According to the Supreme Court of India, our constitution is modelled on the British Parliamentary system where the executive is deemed to have the primary responsibility for the formation of government policy and its transmission into law by retaining the confidence of the Lok Sabha.Article 74 and 75 provide the parliamentary system for the centre.Article 163 and 164 provide the parliamentary system for the states.Unlike the Presidential system, in this system, the executives sit in the legislature because they are part of the legislature.Executives can exercise power and stay in the office as long as they have the support of the lower house of the legislature.In India, the Council of Ministers is collectively responsible to the Lok Sabha.Collective responsibility means the council of ministers has joint responsibility for their actions towards Lok Sabha.Even if a decision has been taken by a single minister, under the principle of collective responsibility the whole council of ministers has responsibility for it.
