The observance of Independence Day in 1930 was followed by the launching of the Civil Disobedience Movement under the leadership of Gandhiji. Gandhiji had to call off the movement on 7 April 1934 due to the following reasons:When Indian leaders were arrested, angry crowds demonstrated in the streets of Peshawar, facing armored cars and police firing. Many were killed. A month later, when Gandhiji himself was arrested, industrial workers attacked police posts, government buildings, law courts, and railway stations, and all structures that symbolized British rule. A frightened government responded with a policy of brutal repression. Peaceful satyagrahis were attacked, women and children were beaten, and about 100,000 people were arrested. Hence Gandhiji decided to call off the movement. The main conditions of the pact were that Gandhiji had to call off the Civil Disobedience Movement and he had to attend the Second Round Table conference in London (the Congress had boycotted the first one). If these conditions were adhered to, then all political prisoners (who had not used any sort of violence against the British government) would be released. Gandhiji went to London, but when negotiations broke down, he returned disappointed. Back in India, instead of releasing the political prisoners, the British Government had started a new cycle of brutal repression. With a lot of apprehensions, Gandhiji had to relaunch the movement, which went strong for a year but lost steam in 1934. ?Hence, the correct answer is 7 April 1934.
