The correct chronological order is: First, the Labour Government's victory in Britain (A) in 1945 accelerated the process for Indian independence. Next, the Direct Action Day (C) in 1946 led to widespread communal violence and political tension. The Interim Government's last meeting (B) occurred in 1947, followed by India gaining independence (D) later that year. Finally, the Indian Constitution was signed (E) in 1950, marking the official beginning of the Republic of India.
