What type of remains does a columbarium specifically accommodate?

A columbarium specifically accommodates cremated remains, which are placed in niches designed for that purpose. This structure allows families to store their loved ones' ashes in a respectful and organized manner. The design of a columbarium varies, but it generally consists of a series of small compartments or shelves, where urns containing the cremated remains can be securely stored.

The other options focus on different types of remains or burial methods that do not align with the use of a columbarium. Entire bodies buried in the ground are associated with traditional burials rather than cremation. Animal remains are typically handled in separate facilities or designated areas and do not fall under the typical use of a columbarium, which is primarily for human remains. Likewise, unembalmed bodies requiring refrigeration pertain to preparation for traditional burial rather than the storage of cremated remains in a columbarium. Understanding these distinctions highlights the specific function of a columbarium in the context of funeral practices.
