The correct answer is D) during his 1864 presidential campaign.

Lincoln proposed the Thirteenth Amendment during his 1864 presidential campaign.

After the Emancipation Proclamation of 1863, President Abraham Lincoln knew that he needed to enforce the prohibition of slavery. So the 13th Amendment to the Constitution of the United States was passed on January 31, 1865. The Amendment was ratified on December 6th, the same year. Now, President Lincoln has legislation that prohibited slavery in the United States.
