Within federal government, the B. legislative branch has direct oversight of Federal Reserve Bank.

Explanation:

The Federal Reserve Bank is answerable to the United States Congress for its policies and activities. The Federal Reserve Bank serves to exercise control over banks in the country and to take care that the fluidity of money is not hindered or halted.

The Congress supervises its activities for that there is no partiality done and the decisions taken by Federal Reserve Bank do not harm the economy of the nation.
