Answer:
The correct answer is letter "B": Treasury bills, a money market mutual fund and bank certificates of deposit.
Explanation:
One of the distinctive features of Treasury Bills is that the government does not periodically pay the holder's interest, instead, the securities are priced under face value, which results in a profit at maturity. Treasury bills offer two major benefits: their lack of risk and tax advantages over other investment opportunities.
Mutual funds are a pool of assets put together to reduce risk and provide small investors the opportunity to access a professionally managed investment vehicle. Certificates of Deposit (CDs) require account holders to keep their money for a certain period so they can benefit from higher interest rates.
Therefore, Treasury Bills, mutual funds, and CDs represent the best investment vehicles the 60-year-old man can choose from to generate income while preserving capital.
