How did the state of confederate railroads mainly impact that group's efforts in the civil war? a) numerous rail lines to increase communications between southern cities. b) southern states were able to ship large quantities of agricultural goods to port. c) the existence of rail lines build a feeling of unity among southern states. d) a sparse amount of rails made it difficult to transport southern troops and munitions.

The correct option is D

The supply situation of the majority of the armies of the Confederacy was appalling, even when they were victorious on the battlefield. The central government was short of money for what each state government had to supply to its own regiments. The lack of central authority and the inefficient railroads, combined with the frequent lack of will or inability of the governments of the southern states to provide adequate financing, were key factors in the disappearance of the Confederate army. The Confederation soon lost control of most of its rivers and major ocean ports being captured or blocked. The road system was poor, and the logistics relied increasingly on a heavily overloaded railway system. Union forces destroyed the confederation's transport and communications system as often as possible, knowing it was unable to replenish it. Occasional raids in the North were designed to capture money and supplies.
