Answer:
C. every additional missile will reduce consumer goods production more and more.
Explanation:
As more missiles are being produced, there would be less resources available to produce consumer goods. So, the production of consumer goods would reduce.
The production possibility frontier explains this concept
The Production possibilities frontiers is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.
As more quantities of a product is produced, the fewer resources it has available to produce another good. As a result, less of the other product would be produced. So, the opportunity cost of producing a good increase as more and more of that good is produced.
