Answer:
Bond A
Step-by-step explanation:
Interest rate risk is the likelihood of loss to bondholders emanating from an increase in a bond's market interest rate which is also the yield to maturity.
However, a bond is issued at a premium when its market interest rate is lower than the coupon rate and at a discount when the reverse is the case.
In this instance, bond A was issued at a discount while B was issued at a premium, hence, the market interest rate of Bond A is higher and it has a higher interest rate risk due to its yield to maturity which made it trade at a discount to the face value of $1000 per bond
