a. abolitionists had gradually become more influential in the north.
b. border states threatened to leave the union if slavery was not abolished.
c. leaders of the democratic party demanded that all enslaved people be freed.
d. slaveholders in the north refused to support the union war effort.

Explanation:

Abolitionists in the North were advocating for the end of slavery. Their growing influence and the moral argument they presented made it a more prominent issue. The Union needed to have a strong moral stance, and as abolitionists gained more voice, it became a factor in shaping the Union's goals. Border states were pro - slavery and would not have threatened to leave if slavery was abolished. Democratic Party leaders did not uniformly demand freedom for enslaved people. Also, there were very few slaveholders in the North.

Answer:

A. Abolitionists had gradually become more influential in the North.
