Statement 1 is incorrect: The Simon Commission, officially known as the Indian Statutory Commission, was an all-white commission composed of seven British Members of Parliament. It included no Indian members, which was the primary reason for its widespread boycott by Indian political parties. Statement 2 is correct: Both the Indian National Congress and a faction of the Muslim League led by Mohammad Ali Jinnah boycotted the Simon Commission due to its exclusion of Indians. Statement 3 is correct: Lala Lajpat Rai, a prominent nationalist leader, was injured during a protest against the Simon Commission in Lahore in October 1928, when police used lathis. He succumbed to his injuries about three weeks later.
