A Historian would look for a primary source (option d. ) - the definition of a primary source is that it was written at the time of the event, and not later (this is the secondary choice).

World War I triggered on June 28, 1914. World War 1 was triggered on 28 June 1914 by the assassination of the Archduke Franz Ferdinand of Austria and his pregnant wife Sophie. Archduke Franz Ferdinand of Austria was the nephew of Emperor Franz Josef and heir to the throne of Austria and Hungary. The assassination was planned by a Serbian terrorist group, called The Black Hand and the man who shot Franz Ferdinand and his wife was a Bosnian revolutionary named Gavrilo Princip.
A primary cause of WW1 was a difference over foreign policy. Although the assassination of Franz Ferdinand triggered WW1, that was only the immediate cause. Differences over foreign policy between the major world powers was the underlying cause of the war.
WW1 had many causes:
A tangle of alliances made between countries, to maintain a balance power in Europe, which brought about the scale of the conflict.
The Bosnian Crisis where Austria-Hungary took over the former Turkish province of Bosnia in 1909 angering Serbia.
Countries were building their military forces, arms and battleships.
Countries wanted to regain lost territories from previous conflicts and build empires.
The Moroccan Crisis where Germans were protesting in 1911 against the French possession of Morocco.
World War I was known by a number of different names. Other names for World War 1 include ‘The War to End All Wars’, The War of the Nations, WW1 and ‘The Great War’.
The Americans joined World War 1 after 128 Americans were killed by a German submarine. In 1915, the British passenger sip Lusitania was sunk by a German submarine. In all, 1,195 passengers, including 128 Americans, lost their lives. Americans were outraged and put pressure on the U.S. government to enter the war. President Woodrow Wilson wanted a peaceful end to the war, but in 1917, when the Germans announced that their submarines would sink any ship that approached Britain, Wilson declared that America would enter the war and restore peace to Europe. The United States entered the war on April 6, 1917.
8 million soldiers died in WW1 and 21 million were injured. 65 million troops were mobilized during during the war, 8 million troops died and 21 million troops were wounded. 58,000 British soldiers were lost on the first day at the Battle of the Somme. Chemical weapons were first used in World War I. The chemical was mustard gas.
The United States only spent seven and a half months in actual combat. The U.S. was in the war in actual combat for only seven and a half months during which time 116,000 were killed and 204,000 were wounded. In the Battle of Verdun in 1916, there were over a million casualties in ten months.
By 1918, German citizens were striking and demonstrating against the war. The British navy blocked German ports, which meant that thousands of Germans were starving and the economy was collapsing. Then the German navy suffered a major mutiny. After German Emperor Kaiser Wilhelm II abdicated on November 9th, 1918, the leaders of both sides met at Compiegne, France. The peace armistice was signed on November 11th. By the end of the war four empires — the Russian empire, the Ottoman empire, the German empire, and the Austro-Hungarian empire had collapsed because of the war.
In 1919, The Treaty of Versailles officially ended the WW1. The Treaty required that Germany accept full responsibility for causing the war; make reparations to some Allied countries; surrender some of its territory to surrounding countries; surrender its African colonies; and limit the size of its military. The Treaty also established the League of Nations to prevent future wars. The League of Nations helped Europe rebuild and fifty-three nations joined by 1923. But the U.S. Senate refused to let the United States join the League of Nations, and as a result, President Wilson, who had established the League, suffered a nervous collapse and spent the rest of his term as an invalid.
Germany joined the League of Nations in 1926, but many Germans were very resentful of the Treaty of Versailles. Germany and Japan withdrew from the League of Nations in 1933. Italy withdrew three years later. The League of Nations was unable to stop German, Italian, and Japanese from expanding their power and taking over smaller countries. Many believe World War I never really ended, and that World War II never would have happened if not for WW1.
