Answer:D.$14,100 gain
Step-by-step explanation:
The par value of a bond is $100 when it's issued below the price it's issued at a discount which is a loss to the firm and when it's issued above the par value, it's issued at a premium which is a gain.
The issue of $705,000 means 7050 numbers were issued and retiring it $102 means at a premium of $2 per bond and a total of N14,100 gain.
