The statement that best explains 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 combined nonviolent resistance with noncooperation to undermine British authority while also garnering sympathy and support from the international community in the face of British repression.
