Answer:
Support grew for the abolitionist movement.
Step-by-step explanation:
Harriet Beecher Stowe's Uncle Tom's Cabin tells the story of a slave man named Uncle Tom and his struggles under slavery. The novel deals with themes of discrimination, freedom, the condition of runaway slaves, and the many issues related to slavery and plantation masters.
With the passing of the Fugitive Slave Act, the liberty and even the life of slaves, runaway slaves and those desiring their freedom came crushing. This law allows a runaway slave to be captured and given back to their masters, at times being punished till death. So, with Uncle Tom's Cabin, the condition of slaves and their very survival came to be put to the fore. It helped build and grow support for the abolitionist movement and the freedom of slaves.
Thus, the correct answer is the first option.
