A. Lord Mountbatten
B. Sardar Patel
C. Lord Ripon (Correct)
Lord Ripon is known to have granted the Indians first taste of freedom by introducing the Local Self Government in 1882. His scheme of local self government developed the Municipal institutions which had been growing up in the country ever since India was occupied by the British Crown. He led a series of enactments in which larger powers of the Local self government were given to the rural and urban bodies and the elective people received some wider rights.
Lord Ripon is known as Father of Local Self Government in India.
This was not enacted by any act, it was a resolution that was passed in 1882.
