Answer:
A. better industrial resources
Step-by-step explanation:
World War I was a milestone in the history of mankind. It was the first war of the twentieth century and the first conflict in a state of total war - one in which a nation mobilizes all its resources to make combat possible.
The Allies (a group formed by Russia, Great Britain, and France) were countries that had many industrial resources and had a stable economy and vast territory. The industrial power of these countries gave them a great advantage over the Entente Axis (formed by Germany, Austria-Hungary, Ottoman Empire and Italy). The Entente Axis, with the exception of Germany, was formed by countries with a weak and deficient industrial sector, in relation to the Allied Axis.
