Final answer:
If bonds are issued initially at a premium and the effective-interest method of amortization is used, the interest expense will decrease in the earlier years.
Step-by-step explanation:
If bonds are issued initially at a premium and the effective-interest method of amortization is used, the interest expense will decrease in the earlier years.
The effective-interest method of amortization allocates the premium or discount on the bonds over the life of the bonds, using the effective interest rate. In the case of bonds issued at a premium, the premium amount is subtracted from the interest expense each year, resulting in a lower interest expense in the earlier years.
Therefore, option a) Interest expense will decrease in the earlier years is correct.
