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 proposal to reconstruct the Viceroy’s Executive Council was advanced by Lord Wavell at the Simla Conference (the Wavell Plan) in June 1945. The Wavell Plan envisaged that, “with the exception of the governor‑general and the commander‑in‑chief, all members of the executive council were to be Indians,” and sought equal Hindu‑Muslim representation and nomination of party representatives for council seats [1]. The Shimla (Simla) Conference thus proposed reconstituting the Viceroy’s Executive Council as an interim government, although the conference ended without agreement between Congress and the Muslim League [2]. Hence the correct choice is the Simla Conference (Wavell Plan).
