Final answer:
The interest-rate risk of a coupon bond is lower when the bond's coupon rate is higher.
Step-by-step explanation:
In the context of a coupon bond, the interest-rate risk refers to the risk that the bond's value will decrease when interest rates rise.
The interest-rate risk of a coupon bond is lower when the bond's coupon rate is higher. This is because a higher coupon rate means that the bondholder will receive a larger amount of interest payments, which helps offset any potential decrease in bond value due to rising interest rates.
Therefore, option 1) Coupon rate is higher is the correct answer.
