Answer :
Nullification refers to the idea that states have the right to declare federal laws invalid within their borders.
Effectively refusing to enforce them. The concept was first proposed by Thomas Jefferson and James Madison in 1798 Virginia and Kentucky Resolutions in response to the Aliens and Sedition Acts passed by federally controlled legislatures.
The idea of cancellation was revived by state advocates in the early 19th century. They argued that states have the right to revoke federal tariffs they find unduly burdensome.
Separatism, on the other hand, refers to states leaving the United States and creating independent states. The issue of secession became a major issue in the United States in the run-up to the Civil War in 1861, when 11 Southern states finally seceded and formed the Confederate States of America. The Civil War was fought partly over the issue of secession and retention of the Union.

1. The Virginia and Kentucky resolutions proposing the idea of repeal were in response to the Alien and Sedition Acts passed by federally controlled Congresses in 1798. These laws were intended to quell political opposition. It was seen by many as an attempt to restrict freedom of expression.
2. Nullification Crisis occurred when South Carolina nullified federal tariffs within its borders and threatened to secede if the federal government tried to enforce the tariffs. The crisis was finally resolved by a compromise in which tariffs were gradually reduced.
3. The issue of secession was a major issue in the United States leading up to the Civil War. In 1861, 11 of her southern states seceded from the Union, and the Civil War broke out. The Union eventually defeated the Allies and kept the United States as a single nation.
