Which of the following settings would induce the Fed to raise the discount rate?

• For the last three months there has been a decline in the federal funds market which triggered interest rates dipping below the discount rate.
• There has been a surge in loan demand from customers, but banks have been unable to secure enough money on the federal funds market to meet the new demand level.
• There has been an increased demand in the federal funds market which triggered interest rates increasing far above the discount rate.
