The correct answer is: C. March 5, 1931.
The Gandhi-Irwin Pact, also known as the Delhi Pact, was an agreement between Mahatma Gandhi and Lord Irwin, the Viceroy of India, signed on 5 March 1931. The pact ended the Civil Disobedience Movement, which had been launched by Gandhi in 1930. The pact granted some concessions to the Indian National Congress, including the release of political prisoners and the lifting of restrictions on civil liberties. However, it did not meet all of the Congress’s demands, such as dominion status for India.
The pact was a significant step forward in the Indian independence movement. It showed that the British government was willing to negotiate with the Congress, and it paved the way for the Round Table Conferences of 1930-32. However, the pact also had its limitations. It did not address the fundamental issue of Indian independence, and it failed to satisfy the more radical elements of the Congress. Nevertheless, the Gandhi-Irwin Pact was a major achievement for Gandhi and the Congress, and it helped to bring India one step closer to independence.
The other options are incorrect because they are not the dates on which the Gandhi-Irwin Pact was signed.
