The president's role in foreign policy increased largely because:
a Congress proved so inept in foreign affairs that the american people demanded a change
b America became more of a world poer
c of the need to coordinate national economic poicy and foreign policy, a task to which the presidency was well-suited
d of the desire of US business to expland into Latin America and Asia, which required executive action at the highest level
I think C is the answer
