The correct option is A Jinnah insisted that all Muslim members of the Executive Council must be nominated by Muslim league.
The Shimla Conference was held from 25 June to 14 July and was attended by 21 leaders. The notable among them were Mahammad Ali Jinnah of Muslim league, Congress President Maulana Abul Kalam Azad, Jawaharlal Nehru, Liaguat Ali Khan, Master Tara Singh and Bhulabhai Desai. The conference began on a hopeful note but ultimately broke down due to the instance of Jinnah that the Muslim league alone represent Indian Muslim and hence no non-league Muslim member could be nominated to the Viceroy’s Executive Council.
