Which of these was a consequence of the Civil War?

Question

A- General William Tecumseh Sherman's March to the Sea destroyed Southern transportation lines.
B- President Lincoln's Gettysburg Address persuaded the South to disarm and surrender.
C- Maryland became a territory due to the writ of habeas corpus.
D- The Southern states gained a new primary source of income.

I think it is A but I just want to be sure

Answer 1

I meant D, I think it is D but I just want to be sure***

Answer 2

I don't think it was D. If it is, what was this new source of income?

Answer 3

Oh, okay your right, D wouldn't make much sense.

Answer 4

So then it is A

Answer 5

I think A is the answer -- but I don't like it either. I don't think Sherman's march destroyed all or even a large part of Southern transportation lines.

Answer 6

Okay I just looked back at my notes, it included a passage and it helped me determine that the best answer is A, thank you for your help

Answer 7

You are welcome.
