Amortization of discount on bonds payable (bond discount) results in which of the following?

A) A decrease in bond interest expense
B) An increase in net income
C) An increase in the carrying value of the bond
D) An increase in stockholders' equity due to the decrease in bond interest expense

Amortization of bond discount results in an increase in the carrying value of the bond, which represents the bond's value on the balance sheet. This is because discount represents the difference between the face value of the bond and the amount paid for it, and this difference decreases over the life of the bond as the discount is amortized. It does not affect bond interest expense or net income, and it does not result in an increase in stockholders' equity.
