One of the biggest trials for andrew jackson while he was the president of the united states was the nullification crisis, which involved south carolina refusing to obey new federal tax laws on imports. select the best answer below that describes both how south carolina protested the federal taxes, and how president jackson responded:

a. south carolina vowed to stop international trade, which would hurt america's economy. jackson responded by canceling the federal tax only for south carolina.
b. south carolina threatened to secede from the united states if jackson did not cancel the import taxes. jackson responded by threatening war if south carolina did not comply with federal laws.
c. south carolina said that it would pay the taxes, but at a reduced rate. jackson went into a fit of rage and barred federal education aid to south carolina for two years.
d. south carolina promised to obey the taxes only if jackson promised to repay south carolina over a ten year period for any decrease in imported commerce. jackson agreed.

The right answer is b.

Explanation:

The Nullification Crisis of 1832-33 was a case where the powers of a state collided with the powers of the federal government. South Carolina did not want to accept and apply some federal-approved taxes. It attempted to declare null and void within the sate federal tariffs of 1828 and 1832.

explanation:

there are two statements that are incorrect.

1. the marshall plan was a lend lease program. it was an economic plan that europe redevelop itself after wwii.

2. einstein didn't really do anything to further the allied cause in building the bomb. he merely sent a letter to fdr telling him (in 1939) that if the united states entered the war, perhaps it would be wise to build the bomb before germany did. i would say this answer is incorrect, but when america entered the war 2 years later, fdr thought it might be a good idea to take einstein's advice.

the 4th choice is definitely so wrong that is likely the single answer of this question

whose power in the senate is equal to the power of the speaker of the house?
