Answer:
The correct answer is B- Nullification was a theory espoused by John C. Calhoun which stated that states had the right to decide which national laws they would accept.
Step-by-step explanation:
John C. Calhoun formulated the Nullification theory in the interest of the southern states, which said that individual states had the right not to implement federal laws that were harmful to them.
In the Nullification Crisis of 1832, which concerned the federal customs laws of 1828 and 1832, even federal troops were deployed in South Carolina when it first threatened secession. In this crisis, Calhoun acted as spokesman for the southern states, and became the first Vice President to resign from office.
