Step-by-step explanation:
The goal of the anti-slavery movement through the 1840s was a) Immediate abolition of slavery.
In the early decades of the 19th century, several groups known as colonizationists emerged. These groups sought to remove blacks from the United States either through emigration or through the creation of colonies in Africa. However, abolitionists, such as William Lloyd Garrison, advocated for immediate emancipation and the end of slavery through moral suasion and promoting the idea of a multiracial society of equals.
While colonizationists favored the gradual end of slavery, the overall goal of the anti-slavery movement was the immediate abolition of slavery.
