Final answer:

Step-by-step explanation:
The Western Front during World War I was located in several countries, but the correct answer to the question is b) France. The Western Front was defined by a long line of trenches that stretched from the English Channel, through unneutral Belgium and northern France, and down to the Swiss border. This region saw some of the most intense fighting of the war, as both the Entente and the Central Powers fought fiercely over this territory. The infamous trench warfare that characterized much of World War I was particularly notable on the Western Front, with both sides suffering heavy losses for years over small territorial gains.
Troops from other nations, including those of the British Empire from places such as Australia and New Zealand, fought alongside the French and British. However, Italy, while initially part of the Triple Alliance with Germany and Austria-Hungary, did not participate in the Western Front at its start and joined the Triple Entente of France, Great Britain, and Russia in 1915.
