Which of the following is required for transporting a body?

Transporting a body requires it to be in a securely closed container, which ensures both dignity for the deceased and compliance with legal and health regulations. A securely closed container serves to prevent any contamination and also protects the body during transit. This requirement is fundamental to maintaining public health standards and honoring the deceased's memory appropriately.

The other options involve specific requirements that are not mandated by law. For instance, there is no requirement that the transport box be decorative or made solely of wood; in fact, a variety of materials can be used for transport containers as long as they meet the required standards. Additionally, labeling only the name of the deceased is insufficient, as other information may be necessary for proper identification and handling during transport. Therefore, the necessity of a securely closed container is a key regulatory aspect of body transport in Missouri.
