The correct answer is option 3: Both 1 and 2.

In the context of the Indigo revolt, statement 1 is correct. The Indigo revolt was a movement against the exploitative indigo plantation system in Bengal during the colonial era, and it gained significant support from the intelligentsia. The intelligentsia played a crucial role in raising awareness about the grievances of the indigo cultivators and organizing protests against the British landlords.

Statement 2 is also correct. After the revolt, the colonial authorities recognized the importance of addressing the grievances of the indigo cultivators. As a result, they established the Indigo Commission to investigate the issues and concerns raised during the revolt. The commission was intended to assess the impact of the indigo system on the cultivators and to propose reforms to address the injustices.

Therefore, both statements 1 and 2 are correct as they accurately relate to the Indigo revolt and the subsequent actions taken by the colonial authorities.
