Hey! Your answer would be 1,4,5. Because in the text,”Jackson Policies” it states ,”South Carolina was very displeased with the new tariff and, at a special convention, issued the Ordinance of Nullification. The ordinance declared that the tariffs of 1828 and 1832 were unconstitutional and, therefore, null and void. Any attempt to enforce the law would be just cause for the secession of the state from the Union.”
So that means
1- They were unconstitutional.
4- They were null and void.
5- They were grounds for the secession.
Hope you have a wonderful day!
