Answer:
The correct answer is A. The southern delegates of the Democratic Party affirmed that slavery should be based on popular sovereignty.
Explanation:
When Jackson left the Presidency, the Democratic Party became increasingly conservative; the party was very popular in the southern states of the country for its defense of the rights of the states against federal power, but this resulted in southern white politicians having an enormous weight within the organization and making it a defender of slavery.
The democrats of the South defended the institution of the slavery of the blacks, and the majority of the democrats of the North contemplated and did not dare to oppose their companions of the South.
