Answer:
C) the rapid expansion of government programs under the New Deal and mobilization for World War II.
Step-by-step explanation:
This is the option that best addresses Franklin D. Roosevelt's expansion of federal power in the 20th century. The expansion of government programs under the New Deal is the first example because this expansion was done at the federal level. The federal government was able to gain significant access to areas that were usually considered jurisdiction of the state government. Moreover, mobilization for World War II similarly took place at the federal level with little impact from state and local governments.
