In Lincoln's Gettysburg Address, which of the following lines best expresses the connection Lincoln makes between the sacrifice already made at Gettysburg and the work still to be done for the sake of preserving the Union?

A. "The world will little note, nor long remember, what we say here, but it can never forget what they did here."
B. "It is rather for us to be here dedicated to the great task remaining before us... that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion..."
C. "It is altogether fitting and proper that we should do this. But, in a larger sense, we cannot dedicate...we cannot consecrate..."
D. "We cannot hallow this ground. The brave men, living and dead, who struggled here have consecrated it, far above our poor power to add or detract."​
