Answer:
D.The yield-to-maturity is less than the coupon rate.
Explanation:
Whenever the yield to maturity is less than the bond's coupon rate, bond market value is greater than par value ( premium bond), these applies just as the question states that the premium bond pays $60 in interest annually in seven years and the bond was issued originally 3 years ago at par
in other cases when a bond's coupon rate is less than its yield to maturity, then the bond is selling at a discount and when a bond's coupon rate is equal to its yield to maturity. the bond is selling at par.
