Correct option is D. Abdul Gaffar Khan
On 6 April he reached Dandi, and ceremonially violated the law, manufacturing salt by boiling sea water. This marked the beginning of the Civil Disobedience Movement. How was this movement different from the Non-Cooperation Movement? People were now asked not only to refuse cooperation with the British, as they had done in 1921-22, but also to break colonial laws. Thousands in different parts of the country broke the salt law, manufactured salt and demonstrated in front of government salt factories. As the movement spread, foreign cloth was boycotted, and liquor shops were picketed. Peasants refused to pay revenue and chaukidari taxes, village officials resigned, and in many places forest people violated forest laws going into Reserved Forests to collect wood and graze cattle.
Worried by the developments, the colonial government began arresting the Congress leaders one by one. This led to violent clashes in many palaces. When Abdul Ghaffar Khan, a devout disciple of Mahatma Gandhi, was arrested in April 1930, angry crowds demonstrated in the streets of Peshawar, facing armoured cars and police firing. Many were killed. A month later, when Mahatma Gandhi himself was arrested, industrial workers in Sholapur attacked police posts, municipal buildings, lawcourts and railway stations all structures that symbolised British rule. A frightened government responded with a policy of brutal repression. Peaceful satyagrahis were attacked, women and children were beaten, and about 100,000people were arrested.
In such a situation, Mahatma Gandhi once again decided to call off the movement and entered into a pact with Irwin on 5 March 1931.By this Gandhi-Irwin Pact, Gandhiji consented to participate in a Round Table Conference (the Congress had boycotted the first Round Table Conference) in London and the government agreed to release the political prisoners.
