At the outbreak of World War I, the Allies had very good strategic plans prepared on how they would counter their enemy. Moreover, they had a thriving industrial economy and knew beforehand war was brewing up (although Germany at the time was capable of building immense amounts of required goods).
An unlimited amount means that there would always be more of it: so they can't run out of it, there will always be more! and since they can't run out of it, they don't have to worry or make choices - they can just use it without any limits and thinking about it.
So the correct answer is
a. have to place limits on its use.
