You bought a 25-year annual coupon bond one year ago. The coupon rate of the bond is 4.8%, the (initial) YTM was 7%, and the face value of the bond is $1,000. Today, you sold the bond (right after the coupon payment). If your holding period return (HPR) is 12.3%, what is the yield to maturity (YTM) when you sold the bond? (Note: Round your answer to two decimals) \begin{tabular}{c} 6.76% \\ \hline 6.90% \\ \hline 6.59% \\ \hline 6.43% \\ \hline 6.22% \end{tabular}
