Final answer:
Germany was most likely pursuing a policy of militarism as suggested by Kaiser Wilhelm's efforts to expand the German navy to match Great Britain's naval power in the lead-up to World War I.
Step-by-step explanation:
During the years leading up to World War I, Kaiser Wilhelm of Germany sought to expand his country's navy to compete with that of Great Britain. This suggests that Germany was most likely pursuing a policy of militarism. Militarism is the belief in building a strong military to defend or aggressively promote national interests. Kaiser Wilhelm's aggressive naval expansion, aimed at matching or surpassing the Royal Navy of Great Britain, was a classic example of militarism. This naval race contributed to the tensions among European powers, exemplified by the construction of Dreadnought-class battleships, and was one aspect of the broader European arms race at this time.
