South Carolina eventually repealed its Ordinance of Nullification in exchange for the passage of a congressional bill giving the president the power to collect taxes by force. the immediate elimination of all tariffs and a federal declaration that nullification was constitutional. the passage of a congressional bill removing the power of the president to collect taxes by force. the federal elimination of the Tariff of 1828 and a gradual reduction on import taxes over a decade

The question is asking about the historical event where South Carolina repealed its Ordinance of Nullification. The Ordinance of Nullification was a declaration by the South Carolina legislature that the federal Tariff of 1828 was unconstitutional and therefore null and void within the state. This event was part of the Nullification Crisis, which was a conflict between the federal government and the state of South Carolina over the issue of tariffs. The crisis was resolved when Congress passed a compromise tariff in 1833, which gradually reduced the tariff rates over the next decade. This compromise led to the repeal of the Ordinance of Nullification by South Carolina. The correct answer is the one that accurately reflects this historical event.
