The trustee, in this case Joe George, represents the bondholder. The role of a trustee in a bond issuance is to act as a representative for the bondholders. This is because it can be resource-intensive for a bondholder to monitor the activities of the bond issuer and to ensure that the issuer is not violating the terms of the bond indenture. The trustee, therefore, steps in to perform these duties on behalf of the bondholders. These duties include authenticating the bonds at the time of their issue, keeping track of the bonds sold and those still outstanding, ensuring that the issuer does not exceed the authorized principal, and verifying that the issuer is maintaining the required ratios. By performing these duties, the trustee helps to protect the interests of the bondholders and ensure that the bond issuer is adhering to the terms of the bond indenture.

Choice A is incorrect. The bond issuer is not represented by the trustee. The issuer is the entity that sells the bonds to raise funds, and it's their responsibility to maintain certain ratios and not surpass the authorized principal. The trustee's role is to ensure that these responsibilities are met.
