Which of the following statements is a benefit of zero-coupon bonds maturing in 20 years?

A zero-coupon bond does not make periodic interest payments. Instead, it is issued at a deep discount to par and matures at face value. Because there are no periodic coupon payments to reinvest, reinvestment risk is not a factor in the same way it is for coupon-paying bonds. Choice C is correct. Choice A is incorrect because zero-coupon bonds do not provide current income. Choice B is incorrect because interest rate risk is significant for long-term zero-coupon bonds; their prices can be highly volatile when interest rates change because all cash flow is received at maturity. Choice D is generally incorrect for taxable zero-coupon bonds because investors may owe tax annually on imputed or accreted interest even though no cash interest is received. The SIE outline covers debt instruments, coupon value, par value, yield, varying maturities, and risks including interest-rate and reinvestment risk. This question focuses on the structural feature of a zero: no interim cash flow means no interim coupon reinvestment decision. Reference: Section 2.1.2 Debt Instruments; Section 2.2 Investment Risks.
