The correct answer is C. stated interest rate.
The coupon rate is the interest rate that a bond issuer agrees to pay to bondholders on a regular basis, usually semi-annually. It is also known as the nominal interest rate or the stated interest rate. The coupon rate is typically fixed for the life of the bond, but it can be floating, meaning that it is tied to an index such as the prime rate or the London Interbank Offered Rate (LIBOR).
The market interest rate is the interest rate that borrowers pay to lenders for loans. It is determined by supply and demand in the market for loans. The market interest rate is usually higher than the coupon rate on a bond because there is a risk that the bond issuer will default on its payments.
The current yield is the annual interest income that a bondholder receives divided by the current market price of the bond. It is a measure of the return that an investor can expect to receive from a bond if they hold it to maturity.
The yield to maturity is the total return that an investor can expect to receive from a bond if they hold it to maturity. It is calculated by taking into account the coupon rate, the market price of the bond, and the time until maturity.
