When can a body be cremated according to the law?

Cremation laws in Missouri specify that a body can only be cremated after obtaining the necessary permits and authorizations, which include a written authorization from the medical examiner in certain circumstances. This is particularly relevant in cases where the cause of death is unclear or involves any legal inquiries. The involvement of the medical examiner ensures that any potential issues regarding the cause of death are addressed before the cremation occurs, thus protecting public health and legal standards.

The other choices do not align with the specific legal requirements. While family approval and timing related to funerals or memorial services may be considerations in the cremation process, they do not fulfill the legal prerequisites mandated by law. Option C highlights the critical step in the legality of cremation, making it the correct answer in the context of Missouri law.
