Which one of the following suggested the reconstitution of the Viceroy’s Executive Council in which all the portfolios including that of War Members were to be held by the Indian leaders?

The correct answer is B, the Simla Conference of 1945, which was based on the Wavell Plan. Lord Wavell proposed a complete reconstitution of the Viceroys Executive Council. Under this plan, all portfolios except that of the Commander in Chief were to be held by Indian leaders. This specifically included the position of the War Member, which was a significant shift from previous proposals. While the Cripps Proposal of 1942 had suggested Indian representation, it had explicitly reserved the defense portfolio for the British. The Simla Conference was the specific instance where the proposal was made for Indians to take over all portfolios, including the functions previously held by the War Member, within the framework of the interim setup.
