Answer:
III). Given time to maturity and yield to maturity, the duration of a bond is higher when the coupon rate is lower.
Step-by-step explanation:
Duration and convexity are two items associated with the management of the risk exposure concerned with fixed-income investments.
Duration is used to check the reaction of the bond in terms of interest rates change. Convexity, on the other hand, is concerned with the correlation between the price of a bond and its yield in connection to the change in interest rates.
A bond's duration is lower when its coupon rate is higher and vice versa because of the influence of a coupon payment being high when made early.
