Answer:
B. We have spent millions of dollars, and thousands of lives have been lost, and we have nothing to show for​.
Step-by-step explanation:
The event at the Appomattox Court House was important in the history of America as it was the place where the Confederates surrendered to the Union. The surrender of General Robert E. Lee and his men to Union General Ulysses S. Grant ended the American Civil War.
In the context of the war, it is important to note that the South and the North contradict heavily especially on the issue of slavery. So, with the Southern army surrendering to the North's, we can easily assume that any Southerner won't be happy about it.
So, the predicted reaction of the surrender will be option B.
