Answer to Question 1

C

Answer to Question 2

Sometimes the federal funds market can fail. For example, during a financial panic, banks with excess reserves do not know who they can trust. They don't know which banks are solvent and which banks are not. Accordingly the banks with excess reserves may be unwilling to lend these reserves out. In such a crisis, the Fed can step in and provide reserves to the banks that need them and is hence referred to as the lender of the last resort.
