The most accurate response regarding how satyagraha helped India achieve independence is:
The noncooperative elements of satyagraha negatively impacted British influence in India. The nonviolent elements created international support after violent responses from the British.
This response captures the essence of satyagraha, which involved nonviolent resistance and civil disobedience against British rule. The noncooperative measures, such as boycotts and protests, weakened British authority and influence, while the nonviolent approach garnered sympathy and support from the international community, especially following the brutal suppression of peaceful protests by the British authorities. This combination was instrumental in pressuring the British to negotiate Indian independence.
