Explanation:

The Federal Reserve (Fed) influences the money supply by setting interest rates (e.g., federal funds rate) and acts as a lender of last resort to banks (e.g., through discount window lending). Overseeing loan collections/payments is not a Fed role. The Fed does not dictate loan terms or offer investment advice.

Answer:

A. manipulating interest rates and acting as a lender to banks.
