Answer:
A. Pay interest.
Step-by-step explanation:
Previously, all of these choices were functions of a bank, though, paying interest was removed because there was no direct link, hence, banks are immune if rates are to be raised by the federal government.
Though, banks may pay interest in terms for loans or other factors, such as when you leave a certain amount of money in your account, as the bank does whatever it does necessary, it will pay interest back to you over time.
