The correct answer is option 2 - Government of India Act 1909. This act, also known as the Morley-Minto Reforms, introduced the concept of elected representation in the Indian legislature for the first time. The act provided for the incorporation of elected members in the Imperial Legislative Council, as well as in the Provincial Legislative Councils. However, it is important to note that the elected representation introduced by this act was limited and did not grant universal suffrage. It only allowed certain privileged classes and communities to elect their representatives. This act was a step towards political reform in India and laid the foundation for further developments in the governmental structure of the country.
