The correct response is:
The Federal Open Market Committee oversees open market operations and sets the target federal funds rate, while the Federal Reserve district banks overlook the banking industry and implement the policies from the Federal Open Market Committee.
This response accurately reflects the distinct roles of the FOMC and the Federal Reserve district banks in the context of U.S. monetary policy. The FOMC is responsible for the overall direction of monetary policy, including interest rates and open market operations, whereas the district banks play a critical role in executing those policies and monitoring their impacts at the local level.
