Answer:
The correct answer is A. The president that followed a policy of reducing the role of the federal government in managing state affairs was Ronald Reagan.
Step-by-step explanation:
During his presidential campaign, Reagan declared "I believe in the rights of states" and "I think we have distorted the balance of our government by giving powers that were never believed to be given in the Constitution to the federal government." He continued promising to "restore to the states and local administrations the power that by right belongs to them."
