The war on the western front was a stalemate by 1916. What was the effect of this development? A) The Germans were able to gain the advantage.
B) Neither side was able to make progress in the war.
C) The British were able to take German lands.
D) The French troops suffered fewer casualties than the Germans.

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.
