The correct option is C The debts increased and the peasants were not able to pay back.
The peasants were forced to grow indigo. They received an advance amount for cultivation, but it was not sufficient, thus leading to increasing debts. The unrest amongst the peasants gave rise to the “Neel Bidroha”, or the Indigo Revolt. It started with a strike by peasants in a village in the Nadia district of Bengal.
