I believe the answer is B only because suffrage means to vote. But it could also include D so I'm not 100% sure.
Correct answer choice is :
C) The Fugitive Slave Act
Explanation:
The south got by the strengthening of the fugitive slave law, the north got a new free state, California. Texas lost empire but was paid with 10 million dollars to pay for its debt. Slave trade was banned in Washington DC, but slavery was not. One of the parliamentary bills that were passed as part of the Compromise of 1850 was a new variant of the Fugitive Slave Act. At first, Clay proposed a treasury bill including these measures. Calhoun criticized the plan and asked that the North cease its efforts to restrict slavery.
The protestant Reformation was a religious movement of the 16th century that began as an attempt to reform the Roman Catholic Church and its results were the creation of Protestant churches.
Hope this answer your question
Slavery was most common in the south because of tobacco, cotton, sugar cane, and etc which was not grown in the north
