Both statements I and II regarding the Non-Cooperation Movement are correct and encapsulate its aims and strategies. The movement, initiated by the Indian National Congress in response to the oppressive policies of the British government, aimed to attain 'Swaraj' (self-rule) through legitimate and peaceful means, reflecting the organization’s commitment to non-violence. Furthermore, the planned phased implementation—culminating in civil disobedience and non-payment of taxes if Swaraj was not achieved within a year—demonstrates the strategic approach of the movement, which sought to mobilize the masses while maintaining a structured escalation in response to government repression. This two-pronged strategy highlights the Congress's commitment to achieving independence through a nonviolent framework, an essential theme in India's struggle for freedom.
