The correct option is C 2 and 4 only
Explanation:
The Indian National Army trials (INA trials), which are also called the Red Fort trials, were the British Indian trial by courts-martial of a number of officers of the Indian National Army (INA) between November 1945 and May 1946, for charges variously for treason, torture, murder and abetment to murder during World War II. The first, and most famous, of the approximately ten trials held in the Red Fort in Delhi. So altogether ten trials took place, and in the first and most celebrated one at Red Fort in Delhi, three officers-P.K. Sahgal, G.S. Dhillon and Shah Nawaz Khan-were charged of treason, murder and abetment of murder.
Points 2 and 4 are correct: The AICC meeting in September 1945 decided to defend the accused in the INA trial-the "misguided patriots"-and announced the formation of a Defence Committee, consisting of some legal luminaries of the day, like Tej Bahadur Sapru, Bhulabhai Desai, Asaf Ali (Not Aruna Asaf Ali), and also Jawaharlal Nehru.
Points 1 and 3 are incorrect: Aruna Asaf Ali and Dr. Ambedkar were not a part of this committee.
