The Federal Reserve System

b. is run by a congressional committee.
c. regulates only national banks.
e. None of these answers is correct.

I would say C..

I agree.

BUT...

In the current system, private banks are for-profit businesses but government regulation places restrictions on what they can do. The Federal Reserve System is a part of government that regulates the private banks

To verify whether your answer is correct, let's go through each option:

a. "is run by a congressional committee": This statement is incorrect. The Federal Reserve System is not run by a congressional committee. While it has a close relationship with Congress and undergoes regular oversight, it is an independent entity.

b. "regulates only national banks": This statement is incorrect. The Federal Reserve System regulates not only national banks but also state-chartered banks, foreign banks operating in the United States, and various other financial institutions.

c. "None of these answers is correct": This statement is correct. None of the options provided is entirely accurate.

Therefore, your answer of "C" is correct. The Federal Reserve System is not run by a congressional committee, nor does it solely regulate national banks. It consists of a combination of regional Federal Reserve Banks and the Board of Governors in Washington, D.C., and its responsibilities extend beyond national banks.
