The correct answer is option 2, the British Parliament. The Parliament of India is primarily based on the model of the British Parliament. This means that the structure and functioning of the Indian Parliament is similar to that of the British Parliament.

The British Parliament is a bicameral institution, consisting of two houses - the House of Commons and the House of Lords. Similarly, the Indian Parliament is also bicameral, with two houses - the Lok Sabha (House of the People) and the Rajya Sabha (Council of States).

In addition, the Indian Parliament follows the principles of parliamentary democracy, where the government is formed by the political party or coalition that has the majority in the Lok Sabha. This is similar to the British parliamentary system, where the majority party or coalition forms the government.

However, it is important to note that although the Indian Parliament is primarily based on the British Parliament, it also has some elements influenced by other parliamentary systems, such as the American Congress and the French Parliament. These influences have been incorporated to suit the specific needs and context of India.
