Answer:
B. the Market Revolution and the Southern expansion of slavery on cotton plantations.

John Calhoun was from South Carolina and represented the interests of the Southerners who had huge cotton plantations with slaves working on them. Cotton was the raw material which the Southerners exported to Britain.
The President, John Quincy Adams in an effort to protect the burgeoning manufacturing industries which were predominantly in North America introduced taxes and tariffs on imported goods in a bid to encourage local manufacturing.
The tariffs didn't go down well with the Southerners as they felt that it would dampen the Southern economy.
Led by vice president Calhoun, they kicked against the tariff hike and introduced the 'Theory of Nullification' in an attempt to fight and scuttle the tariff hike.
