Before a body can be transported, it must be __________ and placed in a constructed casket.

The correct answer is that the body must be embalmed before it can be transported and placed in a constructed casket. Embalming is a process that involves the use of chemicals to temporarily prevent the decomposition of the body, allowing for a more extended period between death and burial or cremation. This procedure helps ensure that the body is in an acceptable condition for viewing and transport, which addresses public health concerns and respects the wishes of the deceased and their family.

While preservation methods exist, they may not be universally required or effective in situations where embalming is mandated for transport. Sealing a body is often related to specific regulations, particularly for interstate transport, but it is typically done after embalming. Burning is associated with cremation and does not apply to the context of preparing a body for transport in a casket. Thus, embalming is the most crucial step to ensure proper handling and adherence to legal and health standards before transporting a body.
