Answer:
B) Neither side was able to make progress in the war.
Explanation:
Trench warfare had been brutal after the failure of the Schlieffen Plan. Germany was fighting French, British, and Belgium forces in the West. Some sides would eventually gain a few feet of the ground after a massive human wave assault but it still led to a stalemate in the end. World War One was a war of attrition and eventually, the Entente would make progress in 1917 when the United States joins the war.
