C. Preventing the resupply of Allied Forces

D. Reducing overall casualties

Answer

C. Preventing the resupply of Allied Forces

Explanation

During World War I, German submarines, also known as U-boats, were primarily used to disrupt Allied supply lines, particularly those coming across the Atlantic Ocean. Their goal was to sink ships carrying food, weapons, and troops to the Allied forces, especially Britain and France. This submarine warfare had a major impact on the war and was a key factor in drawing the United States into the conflict after repeated attacks on civilian and neutral ships.
