The correct answer for this question is option 1: 1909. The Government of India Act of 1909 was also known as the Morley-Minto Reforms or the Indian Councils Act of 1909. It was an important constitutional reform introduced by the British government in India.

The Act was significant because it introduced separate electorates for Muslims, which means that Muslim representatives were elected separately from the representatives of other communities. This provision was made to address the demands and concerns of the Muslim community, who felt that their interests were not adequately represented in the Indian National Congress, which was dominated by Hindu leaders.

The Act also expanded the size of the legislative councils and increased the powers of the councils. It allowed for greater participation and representation of Indians in the legislative process, although the ultimate authority still remained with the British government.

Overall, the Government of India Act of 1909 marked a step towards limited self-governance in India and provided separate representation for Muslims, which laid the foundation for future demands for political rights and autonomy.
