The correct answer is option-2, 1908. Mahatma Gandhi was first arrested during the `Satyagraha` movement in the year 1908. Satyagraha was a nonviolent resistance movement that Gandhi used as a form of protest against British rule in India. It was during the `Satyagraha` in the city of Kolkata (then Calcutta) that Gandhi was arrested for the first time. This movement aimed to promote civil disobedience and passive resistance as a means of achieving independence for India. Gandhi`s arrest marked the beginning of his active involvement in the fight for independence and he would go on to become one of the most important leaders in the Indian independence movement.
