Answer:
B. Step-up/Step-down CD
Explanation:
A bank certificate of deposit (CD) can be defined as a secured form of time-bound deposit and a special low-risk savings account, wherein money (lump-sum) are left with the bank for a specific period of time in exchange for an interest rate premium.
Generally, a certificate of deposit pays a higher interest rate to its holder than the regular savings account because the banks invest the money in a business.
Additionally, the bank certificate of deposit is protected and insured by the Federal Deposit Insurance Corporation (FDIC) for up to $250,000.
A Step-up/Step-down certificate of deposit (CD) is a type of CD that changes the rate of interest for a deposit based on the prevailing market interest rate.
