The correct answer is D. After the Battle of Chancellorsville, the North seemed unlikely to win the war.

Explanation:

The Battle of Chancellorsville was one of the greatest battles of the Civil War, fought near the village of Spotsylvania Courthouse, Virginia between 30 April and 6 May 1863. During this battle, the South's army under Robert E. Lee defeated the much larger Union army under Joseph Hoker.

The battle began when the Union army crossed the Rappahannock River on the morning of April 27, 1863. By April 30 they were near Chancellorsville, and fighting began on May 1st. It continued until the Union army had to retreat on the night of 5 and 6 May.  

It was an important victory for the South, but they lost one of their best generals when Stonewall Jackson was shot by his own troops as he returned to the army at dusk. He died of his wounds a few days later.
