Answer:
The correct answer would be option D, Treasury Bills.
Step-by-step explanation:
Treasury Bills are the certificate given by banks or financial institutions in exchange for your money for a specified period of time. People put their money with the banks for a specific time period, of usually 10 years. A percentage of interest is given to them for keeping their money with the bank for a specified time period. Ideally, people can't redeem their money before the specified time period. They can enjoy the interest amount on their money while keeping it safe and secure. So Treasury Bills are the type of investment that can be redeemed at the end of a specified period of time.
