Correct Answer: (b) 1 and 3 only
Note: Indentured labour were those who were taken out of India as labourers for fixed periods in the British colonies. Their condition was like that of bonded labourers. Gandhiji first raised his voice in favour of indentured labourers in South Africa in 1894. In the year 1914, by the Gandhi-Smuts Agreement, the tax of 3 pounds on these labourers ended. After coming back to India, Gandhi negotiated with Viceroy Lord Chelmsford to end the indentured system and finally in July 1917 the indentured system was banned. Thus statement (1) is correct. After Gandhiji's Dandi March and his breaking of salt law on April 6, 1930, Indians across the country started violating the salt law. In response to this, many congress leaders and Satyagrahis like Jawaharlal Nehru, Mahadev Desai etc. were sent to prison and Indian National Congress was declared illegal by British rule. Thus statement (3) is correct.
