Assume that a noncallable 10-year T-bond has a 12% annual coupon, while a 15-year noncallable T-bond has an 8% annual coupon. Assume also that the yield curve is flat, and all Treasury securities have a 10% yield to maturity. Which of the following statements is CORRECT? a. If the yield to maturity on both bonds remains at 10% over the next year, the price of the 10-year bond would increase, but the price of the 15-year bond would fall. b. The 10-year bond would sell at a premium, while the 15-year bond would sell at par. c. If interest rates decline, the prices of both bonds would increase, but the 10-year bond would have a larger percentage increase in price. d. If interest rates decline, the prices of both bonds would increase, but the 15-year bond would have a larger percentage increase in price. e. The 10-year bond would sell at a discount, while the 15-year bond would sell at a premium.
