The correct answer is Kasturi Ranga Iyengar.Swarajists and No-changersThe Swarajists or the Pro-changers section were led by C.R. Das, Motilal Nehru, Kasturi Ranga Iyengar and Ajmal Khan.Hence, Kasturi Ranga Iyengar was not a No changer.They wanted an end to the boycott of legislative councils so that the nationalists could enter them to expose the basic weaknesses of these assemblies and use these councils as an arena of political struggle to arouse popular enthusiasm.In other words, they advocated end or mend these councils, i.e. if the government did not respond to the nationalist's demands, then they would obstruct the working of these councils.The other school of thought led by C. Rajagopalachari, Vallabhbhai Patel, Rajendra Prasad, and M.A. Ansari came to be known as the No changers.They opposed council entry and end or mend strategy.They advocated concentration on constructive work, and continuation of boycott and non-cooperation, and quiet preparation for the resumption of the suspended civil disobedience program. The No-Changers argued that parliamentary work would lead to neglect of constructive work, loss of revolutionary zeal, and political corruption.Constructive work would prepare everyone for the next phase of civil disobedience.
