(hurry 54 minutes left) : abraham lincoln reacted to the hanging of john brown by a. celebrating his death with speeches endorsing violence against slaveholders. b. advocating that the slave states secede. c. calling for the freeing of all slaves. d. refusing to excuse brown's violent tactics.

D. "Refusing to excuse Brown's violent tactics."

Explanation:

Lincoln is stated as of having thought of Brown as more of a terrorist, and that his violent actions were not the way that people should go about attempting to end slavery.

It makes sense that he would think this as Lincoln needed to get as many Americans on his side for the future whether northern or southern as of course he intended to reunite them. Southerns saw brown as a terrorist and Lincoln could not let himself be known as an advocate of more violence on American soil.
