Answer: B. credit of $28,750 to Discount on Bonds Payable
Explanation:
From the question, we are informed that the face value of the bond is $500,000 while the bond's carrying value is $471,250. The bonds were issued at a discount since the carrying value is less than the face value of the bond.
At the time that the bonds was retired, the unarmotized discount on bond payable will be:
= $500,000 - $471,250
= $28,750
Therefore, the entry to record the redemption will include a credit of $28,750 to Discount on Bonds Payable.
