Correct answer: A. To cut Allied supplies
Explanation: The direct answer is A: German U-boats aimed to cut Allied supplies. A U-boat was a German submarine used in the Battle of the Atlantic during the Second World War. Britain and other Allied countries depended on ships carrying food, fuel, weapons, troops, and raw materials across the Atlantic. German submarines attacked these merchant and supply vessels in an effort to reduce deliveries, weaken Britain, and make it harder for the Allies to continue the war. Option A is correct because it states the strategic purpose of the submarine campaign. Option B is wrong because Germany’s aim was not to give Europe to Japan; the two countries were Axis partners with separate war aims. Option C is wrong because strengthening the League of Nations was not the purpose of submarine warfare, and the League had already been weakened before this conflict. Option D is wrong because U-boats attacked shipping and had no objective of increasing farming in France. The essential chain is submarine attacks → fewer ships and supplies → pressure on Allied war effort. Remember ‘U-boat = underwater boat used against supply lines’; naval strategy here was also an economic and logistics struggle.
