Answer:
D. Individual governors of the Federal Reserve Banks disagreed over policy and were unable to stop the depression.
Step-by-step explanation:
The Great Depression started in August 1929, there were many financial system reforms bu the recession that came in 1937 interrupted any economic recovery.
The Federal Reserve System had a decentralized decision-making structure, because of that, each district had a governor who set the policy for the district. The Board lacked authority and tools to act. This caused ineffectiveness, especially when governors disagreed and took contradictory courses of actions.
