Answer: C
Step-by-step explanation:
The best answer to this question is C. The warfare on the Western Front in World War One was mostly fought in trenches, which resulted in high casualties for both sides. The trenches were a system of parallel ditches dug into the ground for protection from enemy fire. Soldiers would live and fight in the trenches for weeks or even months, often in horrible conditions with little access to food, clean water, or medical care. The Western Front was known for its brutal and prolonged battles, such as the Battle of the Somme and the Battle of Verdun, which resulted in huge numbers of casualties on both sides. The war on the Western Front was a war of attrition, with both sides trying to wear down the other until one side eventually gave up.
