D. all of these answers are correct.

Explanation:

Harriet Beecher Stowe's "Uncle Tom's Cabin" shows the condition and lives of the slaves during the slavery system, the recently passed Fugitive Slave Act and the effects it had on them. Stowe became one of the strongest abolitionists fighting for the rights of the colored people.

Her novel was written just after the government passed the Fugitive Slave Act in 1850, thus making the retrieving of runaway slaves by masters as a legal right. Though this gave the rights to make the slaves return to their masters, it also led to many free slaves being openly forced to be taken back. It also led to mass immigration of slaves to Canada, which led Stowe to write about the reaction of the people about the Act. It also led to the northern states to sympathize with the slaves and gained a lot of supporters for the abolition of the system. Describing slavery as a sin against humanity, Stowe managed to impact a lot of people with her novel, leading it to be one of the main reasons for the Civil War in America.
