Letter C is the correct answer.

Militarism is a philosophy by which the government glorifies the military power. It is known that militarism itself wasn't the only factor that caused the World War I - nationalism and imperialism were, also, strongly linked to it. In order to protect their political and economic interests and create policies, nations needed powerful armies and navies. Thus, militarism led European nations to rely on force to solve diplomatic issues.

Answer choice B also has some truth to it, because the agreements/alliances European nations had made played a part in the start of World War I.  However, honoring such agreements is a political or diplomatic matter, not a direct effect of militarism.   Militarism was the propelling force that led the nations to think that war was the best way to solve the problems that arose.

Explanation/context on how World War I began:

The systems of alliances and military plans which were put in place before World War I presupposed a major war between the countries which were tied together with alliances.  The Triple Entente had Britain, France and Russia as allies.  Germany was part of a group of allies in opposition to the Triple Entente.  Behind these alliances stood the escalating trend of militarization and military planning that the nations were doing, preparing for war with one another.

So here's what happened to start the Great War (World War I).  When an Austrian prince and his wife were assassinated in Serbia, the Austrian Empire threatened the nation of Serbia with retaliatory action (even though the assassination was carried out by a terrorist group, not the Serbian government). Russia responded to Austria's threat, because Russia was bound to protect its Slavic ally, Serbia. Germany responded to the mobilization of Russian troops, and when Germany declared war on Russia in 1914, they implemented the Schlieffen Plan (drawn up by one of their generals), which called for them to go on attack vs. France.  That pulled France and Britain into the war immediately as well, and the war spread and became a global conflict.
