Answer: The lines that best support the idea that President Lincoln's Emancipation Proclamation might be ignored by Confederacy is 2. "…in time of actual armed rebellion against the authority and government of the United States…".
Explanation: In sentence 2, President Lincoln is making reference to the armed rebellion of the confederate states during the Civil War. The Confederacy existed from 1861 to 1865 and it was conformed by seven states that supported slavery in the United States. In that way, these states were against the Emancipation Proclamation issued by Lincoln, which declared that all the slaves living in the South were now free. For that reason, sentence 2 is the one that best supports the idea that Lincoln's Emancipation Proclamation might be ignored by the confederate states.
