What is the name of the board composed of 9 commissioners selected by the Federal Reserve Bank chairman?

The correct answer is the Federal Reserve Board. This board consists of seven members, not nine, who are appointed by the President of the United States and confirmed by the Senate to guide the Federal Reserve System's policies and operations. It oversees the nation’s monetary policy, regulates banking institutions, and maintains financial stability.

The Securities and Exchange Commission, while important, is focused on regulating the securities industry and protecting investors, rather than overseeing the Federal Reserve System. The Commodity Futures Trading Commission is similarly a separate entity that regulates commodity futures and option markets. The Office of the Comptroller of the Currency is responsible for chartering, regulating, and supervising all national banks and federal savings associations, which is distinct from the governance structure of the Federal Reserve.

Understanding the specific roles and structures of these financial regulatory bodies is crucial for comprehending how they interact and function within the broader banking and financial system.
