I answered what i thought were the correct answers but I am unsure, can someone please help, and explain the last one.

A bond investor is analyzing the following annual coupon bonds: Each bond has 10 years until maturity and has the same risk. Their yield to maturity (YTM) is 9%. Interest rates are assumed to remain constant over the next 10 years. Label the curves on the following graph to indicate the path that each bond's price, or value, is expected to follow. Based on the preceding information, which of the following statements are true? Check all that apply. Irwin's bonds have the highest expected total return. The current yield for Irwin's bonds is greater than 9%. Johnson's bonds are selling at par. The current yield for Irwin's bonds is between 0% and 9%. If a bond is selling for a price much lower than its par value, it is most likely that the bond is an outstanding bond
