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?

1. The question asks which proposal suggested the reconstitution of the Viceroy's Executive Council with all portfolios including War Members held by Indian leaders. 2. Simon Commission (1927-30) reviewed the constitution but didn't propose this specific council reconstitution. 3. Simla Conference (1945), convened by Viceroy Lord Wavell based on the Wavell Plan, proposed forming a new Executive Council where all members except the Viceroy and the Commander-in-Chief would be Indians. This closely matches the description, aiming for near-complete Indian control over portfolios (though C-in-C, effectively the War Member, was initially excluded, the intent was maximum Indianization). 4. Cripps Proposal (1942) offered Dominion status and a constituent assembly post-war, not this immediate council change. 5. Cabinet Mission (1946) proposed an interim government and long-term constitutional framework. 6. The Simla Conference (Wavell Plan) is the closest fit to the suggestion described.
