d. that the use of poison gas was a war crime

The correct option is A

The battle of the Marne (also known as the Miracle of the Marne) was a battle of the First World War that took place between 5 and 12 September 1914. The result was an Allied victory over the German army. The battle was the maximum point of the German advance in France and of the persecution to which it subjected the allied armies after the battles of the borders of August and that arrived until the outskirts of Paris. The counterattack of six French campaign armies and the British Expeditionary Force (BEF) along the Marne River forced the German Imperial Army to retreat to the northwest. The battle of the Marne was a strategic allied victory, since it supposed the defeat of the Schliefen Plan, that looked for a fast defeat of France. The German withdrawal that followed is known as the race to the sea and ended with the battle of the Aisne and the closure of the western front by the north, which meant the end of the war of movements and the establishment of a static continuous front that would lead to almost four years of trench warfare.
