Answer:
The correct answer is letter "B": Income bond.
Explanation:
Income bonds or bonds are investment instruments that companies issued with a promissory note of repayment based on a fixed interest rate. While bonds are less riskier than other investment vehicles such as stocks, it would not be convenient for a 60 years-old man looking for safety and a moderate level of income because bonds' repayments depend on the company's profits.
Mutual funds are pools of assets managed by securities professionals. U.S. Government bonds and bond funds are directly issued by the government. Thus, any of these three vehicles would be most convenient for the 60 years-old individual.
