Which of the following is a characteristic of an alternative cremation container?

An alternative cremation container is specifically designed for the encasement of human remains, focusing on providing a respectful and safe environment for the body during the cremation process. The primary function is to facilitate the cremation in a dignified manner. Such containers can be made from various combustible materials that may not necessarily need to be ornate or exhibit long-lasting durability, as the function is strictly for cremation rather than long-term storage.

The other options emphasize characteristics that do not align with the primary purpose of an alternative cremation container. For instance, an ornate design or a requirement for metal construction contradicts the essence of alternative containers, which can include biodegradable materials, cardboard, or wood that prioritizes simplicity and environmental considerations over aesthetic or durability qualities.
