The civil war wasn't self defense, it was a war over the issue of slavery and the rights of the states, so I'd eliminate B. The south actually had the superior military leaders, the North was struggling with that part, so it's not C either.

About <span>6,000,000–11,000,000 people died in the holocaust</span>
