Explanation:

C. Rajagopalchari’s Formula :

• C. Rajagopalachari’s formula (or C. R. formula or Rajaji formula) was a proposal formulated by Chakravarti Rajagopalachari to solve the political deadlock between the All India Muslim League and the Indian National Congress on the independence of British India.
• The League’s position was that the Muslims and Hindus of British India were of two separate nations and hence the Muslims had the right to their own nation.
• The Congress, which included both Hindu and Muslim members, was opposed to the idea of partitioning India.
• With the advent of the Second World War the British administration required both parties to agree so that Indian help could be sought for the war effort.
• C. Rajagopalachari, a Congress leader from Madras, devised a proposal for the Congress to offer the League, the predominantly Muslim region that became Pakistan based on a plebiscite of all the people in those regions where Muslims were in the majority.
