Which entity must approve the bond filed by a cemetery authority managing prearrangement trust funds?

The correct answer is that the bond filed by a cemetery authority managing prearrangement trust funds must be approved by the Cemetery Board. This board is responsible for overseeing the operation of cemeteries and ensuring compliance with regulations related to the management of trust funds for prearrangements.

The bond serves as a financial guarantee that the cemetery authority will fulfill its obligations concerning the prearrangement trusts, which is crucial in protecting consumers' interests. The Cemetery Board's approval acts as a safeguard, ensuring that only qualified entities manage these important funds, thereby maintaining the integrity of the process and protecting the rights of individuals who have prearranged their funeral services.

In this context, the other entities listed do not have the authority to approve this bond. The State Bank typically handles financial transactions but does not oversee cemetery operations. The Department of Health focuses on health regulations rather than cemetery management. Lastly, the Department of Revenue deals with tax-related matters, which are not directly relevant to the approval of bonds for cemetery trusts.
