Answer:
The correct answer is letter "A": The National Security Argument.
Step-by-step explanation:
According to the National Security Argument, it is a threat to depend on another country for economic sustainability purposes. This point of view proposes that self-sufficiency is the only means of progress for a nation. Exceptional cases such as wars are usually cited with this theory to point out that under those circumstances relying on another country -for fuel, for instance- could represent a big drawback.
