Answer:
The answer is Certificate Of Deposit.
Step-by-step explanation:
A certificate of deposit (CD) refers to a product which is usually offered by banks and credit unions and which provides an interest rate premium based on the condition that the customer agrees to leave a lump-sum deposit untouched for a particular length of time.
Almost all consumer financial institutions offer certificates of deposit, but each bank can set its own peculiar certificate of deposit terms and conditions.
