In 1915, during World War I, why did Germany use unrestricted submarine warfare against ships in the eastern Atlantic Ocean, including warfare against ships of both neutral and enemy nations?
A
Germany wanted to stop the British from transporting materials of war on vessels not marked as British vessels but marked with flags of neutral countries.
B
Germany hoped to lure the United States into the war so that Germany could defeat the United States along with the other allies and claim all of those lands for itself.
C
Germany wanted to take over all ships in the Atlantic Ocean and add these ships to its growing naval fleet, which needed extra ships to achieve its goal of global naval supremacy.
D
Germany wanted to capture sailors of every nationality and impress them into their own naval forces so that these sailors could assist Germany in its war effort against the allied powers.
