The correct answer is option 2, 1919. Mahatma Gandhi gave a call for a Satyagraha against the Rowlatt Act in 1919. The Rowlatt Act was passed by the British government in India to suppress political activities and to curb the nationalist movement. It allowed the government to arrest and detain individuals without trial. Gandhi saw this act as a violation of civil liberties and a denial of justice. He called for a peaceful protest known as Satyagraha, which involved nonviolent resistance and civil disobedience. The movement gained significant support from the Indian population and marked a turning point in the fight for independence. It eventually led to the Jallianwala Bagh massacre in Amritsar, which further fueled the freedom struggle.
