Champaran Satyagraha was organised by Gandhiji for which of the following ?

Indigo farmers

The correct answer is Option (2) - Indigo farmers

When Gandhi returned to India from South Africa in 1915 and saw peasants in Northern India oppressed by Indigo planters, he tried to use the same methods that he had used in South Africa to organise mass uprisings by people to protest against injustice. Champaran Satyagraha was the first popular satyagraha movement.
