The question asks about the official Congress negotiators with the Cripps Mission, a British initiative aimed at securing Indian cooperation during World War II in return for independence after war. From the given options, the correct answer is option 3: Pandit Nehru and Maulana Azad.

Option 1, Mahatma Gandhi and Sardar Patel, is incorrect as they were not the official negotiators, despite being integral part of Congress. Similarly, option 2, Acharya J. B. Kripalani and C. Rajagopalachari, is incorrect for the same reason.

Option 4, Dr. Rajendra Prasad and Rafi Ahmed Kidwai, is also incorrect. While both were influential Congress leaders, they were not the primary negotiators with the Cripps Mission.

Only Nehru and Azad, who held significant positions in Congress and had been a part of negotiating team with the British in past, were the official negotiators representing Congress in dialog with the Cripps Mission.
