Answer:
B. Abraham Lincoln
Explanation:
The slave states of Missouri, Kentucky and Maryland were concerns for President Abraham Lincoln as he felt that they might leave the Union and join the Confederate Sates of America. Also, been that he is from Kentucky, he didn't want to be seen as political failure.
The resolution made was intended to maintain and retain Unionists in those slave-holding border states. Also, it was made to reassure the Northerners that would fight to save and protect the Union.
This resolution implied that there would be end to the war upon the return of seceding states with slavery intact.
In July 1861, this resolution was introduced. It was passed by the house immediately after the battle when the Confederate army routed the Union army.
