The correct answer is B) Freedom of the Seas.
This is evident based on America's experience before entering World War I. Before entering this war, over 100 Americans were killed by a German submarine that attacked the British ship called the Lusitania.
Along with that, the Germans would go on to use unrestricted submarine warfare several more times before the US officially entered World War I. At the end of the war, Wilson even addressed this idea in his 14 Points. Wilson's 14 Points were his ideas on how the world should look after World War I was over.
