The correct answer is option 2 - Muslims. The Morley-Minto reforms, also known as the Indian Councils Act of 1909, introduced limited electoral representation for Indians in the British Indian legislative councils. This act provided for separate electorates, which reserved seats for different religious communities. The seats were reserved based on religion, and the largest community that benefited from this reservation was the Muslim community. The reforms were implemented to address the growing demands for political representation by Indians, and the reservation of seats for Muslims was seen as a way to ensure their representation and protect their interests in the legislative councils.
