The correct answer is "Lincoln did not want armed conflict at Fort Sumter, but Davis acted quickly to cripple Union forces".
Lincoln was certainly adamant about avoiding military confrontation over the Fort. His aims were put in preserving the Union, which proved to be extremely hard as the conflicts were started by the sates that had separated or seceded, as well as the first attacks on Fort Sumter.
Davis cared a lot less about preservation and just tried to find the quickest and most effective way to mitigate the conflict. He believed crippling the Union's army would make them leave as they would not have enough time to respond and they'd be at a great disadvantage.
Hope this helps!
