Answer:
c. Franklin Roosevelt and his "New Deal"
Step-by-step explanation:
The New Deal is the oldest of the programs listed in the question, and one of the most transformative.
It ended the limited role that the federal government had with the states because it started a series of federal programs that applied for all states, that transformed American economy and society, and that live up to this day.
For example, the largest government program: Social Security, applies nationally, and was precisely created by Roosevelt's New Deal.
