Answer:
C. II and III
Step-by-step explanation:
The bond was issued with a coupon of 8%. Currently, yield for a similar issue is 7%. Therefore, interest rates have fallen subsequent to the issuance of the bond; or the credit quality of the bond has improved.
When interest rates fall, yields on bonds already trading must also fall. What causes this is a rise in the dollar price of the issue - the bond now trades at a premium.
