The correct answer is option 2: 1930. The Salt Satyagraha, also known as the Salt March or Dandi March, took place in the year 1930. It was a nonviolent protest organized by Mahatma Gandhi against the British salt monopoly in colonial India. The satyagrahis, led by Gandhi, marched for 24 days from Sabarmati Ashram to Dandi, a distance of around 240 miles. The aim of this protest was to challenge the British salt laws and promote the production and use of local salt. The Salt Satyagraha was a crucial event in the Indian independence movement and played a significant role in mobilizing public support against British rule. It marked a turning point in the fight for freedom and inspired millions of people to actively participate in the struggle for independence.
