The correct answer is: 3. Garrison focused on moral persuasion and publishing anti-slavery literature, while Douglass also engaged in political activism and supported working within the political system.
William Lloyd Garrison, a prominent abolitionist, emphasized moral arguments against slavery and used his platform through publications like "The Liberator" to advocate for immediate emancipation. Frederick Douglass, on the other hand, not only used moral persuasion but also actively participated in political activism, including advocating for political rights and working within the political system to achieve abolition and civil rights. The other statements contain inaccuracies regarding their views on the Union, emancipation strategies, and methods of protest.
