During the Salt Satyagraha, in Bihar, along with making salt, people protested against the government by opposing which tax?

Explanation

Mahatma Gandhi began his famous “Dandi March” on 12 March 1930. He left the Sabarmati Ashram with selected companions for Satyagraha. After a journey of 24 days, on 6 April, 1930 at Dandi, he symbolically broke the Salt Law, and the Civil Disobedience Movement began. During this period in Bihar, along with making salt, people also protested against the Chowkidari tax. The protest against the Chowkidari tax was highly successful in Bihar.
