India is a parliamentary democracy based on the Westminster model of ____________.

Correct option is D

The correct answer is (d) the United Kingdom
 India's parliamentary system is based on the Westminster model, which originates from the United Kingdom. This model of governance is characterized by a clear separation between the head of state and the head of government, with the latter wielding executive power.
 In the Indian context, this translates to the President being the nominal head of state, while the Prime Minister serves as the head of government, responsible for running the government and making policy decisions. The system features a bicameral legislature consisting of the Rajya Sabha (Council of States) and the Lok Sabha (House of the People), similar to the British Parliament’s House of Lords and House of Commons.
 The Westminster model in India also incorporates features such as the cabinet being drawn from the legislature, collective responsibility of the cabinet to the legislature, and the leadership of the Prime Minister as primus inter pares, or first among equals, within the cabinet. This model underpins India's democratic structure, facilitating a system of checks and balances typical of parliamentary democracies.
