During the Salt Satyagraha in Bihar, in addition to making salt, the people chose to oppose the government by opposing which tax?

During the Salt Satyagraha of 1930 in landlocked Bihar, because coastal seawater was unavailable, freedom fighters manufactured salt from saline soil (Kharimatti) and simultaneously launched a widespread, powerful no-tax campaign against the 'Chowkidari Tax'. Because Chowkidari Tax is not listed among the options, 'None of the above' is correct.
