Explanation:

• The Wavell Plan was first presented at the Shimla Conference in 1945. It was named after Viceroy of India, Lord Wavell. The Shimla Conference was convened in order to agree on the Wavell Plan for Indian self-government, which provided for separate representations on communal lines. Both the plan and the conference failed on account of the Muslim League and the Indian National Congress not coming to an agreement. Hence option 1st is correct.
