The correct answer is option 3, Agha Khan. The All India Muslim League was founded by Agha Khan in 1906. This political organization was formed to advocate for the rights and interests of Indian Muslims during the time of British colonial rule. Agha Khan played a crucial role in uniting Muslims from different regions and promoting their political representation. Although options 1, 2, and 4 are all important historical figures, they were not directly involved in the founding of the All India Muslim League. Option 1 refers to Maulana Ahmed Ali, who was a prominent Islamic scholar and thinker. Option 2 is Mohammad Ali Jinnah, who later became the leader of the Muslim League and the founder of Pakistan. Option 4 is Hakim Ajmal Khan, a renowned physician and leader of the Indian National Congress.
