Solution:

For the Partition of India and Pakistan, a Partition Committee was formed which was chaired by Lord Mountbatten and its members were Vallabh Bhai Patel, Dr Rajendra Prasad, Liaqat Ali Khan and Abdur Rab Nishtar. Later this committee was replaced by a Partition Council. In this council, Congress was represented by Sardar Patel and Dr Rajendra Prasad, with C. Rajgopalachari as the alternate member. Muslim league was represented by Mohammed Ali Jinnah, Liaqat Ali Khan and Abdur Rab Nishtar as the alternate member. Please note that even after 15 August 1947, this partition council was in existence, but the composition was changed as 2 members from each dominion. Patel and Dr Prasad kept representing Indian Domain even at that time.
