In 1930 and 1931 in which district did the Barahi Congress successfully make the British rule functionless?

The correct answer is: A. Madhubani

The Barahi Congress was a peasant movement that was active in the Madhubani district of Bihar in the early 1930s. The movement was led by Shri Krishna Singh, who was a local leader of the Indian National Congress. The Barahi Congress successfully made the British rule functionless in the district by boycotting British goods, refusing to pay taxes, and organizing strikes and demonstrations.

The Barahi Congress was a significant movement in the history of the Indian independence struggle. It showed that the Indian people were capable of resisting British rule and that they were willing to fight for their freedom.

The other options are incorrect because:

• Bhagalpur is a district in Bihar, but the Barahi Congress was not active in that district.
• Gaya is a district in Bihar, but the Barahi Congress was not active in that district.
• Munger is a district in Bihar, but the Barahi Congress was not active in that district.
