Which of the following describes a product intended to aid in the transportation of deceased individuals?

The Ziegler Case is specifically designed for the transportation of deceased individuals, particularly when it comes to shipping human remains over long distances. This container is often constructed to comply with legal regulations and is intended to provide protection and dignity to the body during transit.

Caskets, while they may be used during a funeral service, are generally not designated solely for transportation purposes. They serve both ceremonial and logistical functions, typically remaining at the funeral home or service location. Cremation containers are also not primarily intended for transportation; they are designed to hold the body during the cremation process itself. Grave markers, meanwhile, serve as memorials at a burial site, rather than aiding in the transport of the deceased.

In summation, the Ziegler Case stands out as the correct answer due to its specific purpose in transporting remains, balancing regulatory compliance with respectful handling.
