Answer: a. government bonds are conducted at the New York Fed's trading desk.
Step-by-step explanation:
The Federal Open Market Committee (FOMC) of the Fed has the responsibility to engage in appropriate Open Market Operations in order to effect the Fed's monetary policy.
The actual responsibility of the buying and selling these securities falls on the New York Fed. As a result, all Fed purchases and sales are done in New York by the New York Fed. This cements New York as the main financial services location for the government.
