The correct option is B Non-cooperation
Non-cooperation movement was an attempt organized by Mahatma Gandhi in 1920 to induce the British government of India to grant self-government, or swaraj, to India. Gandhi gave a call for boycott of foreign goods, surrendering all titles and honorary offices and resign from nominated seats in local bodies, etc. It was suddenly adjourned due to the violent Chauri Chaura incident in 1922.
