What term refers to the building or portion of a building that houses the holding facility and the cremation chamber?

The correct term for the building or portion of a building that houses both the holding facility and the cremation chamber is indeed "crematory." This term specifically identifies the entire structure where cremation processes occur, including areas dedicated to holding remains prior to the cremation and the actual cremation equipment itself.

A crematory is designed to meet specific regulatory standards and is equipped to safely manage the various procedures required for cremation. Understanding this terminology is vital for professionals in the funeral industry, as it directly relates to the legal definitions and responsibilities within the field.

The other terms presented, while related, do not accurately describe this specific facility. "Cremation" refers to the process itself, and "cremation chamber" denotes just the part of the crematory where the cremation takes place, excluding other necessary areas. The "operator of a crematory facility" refers to the individual responsible for the operation of a crematory, not the physical building or structure where the operations are performed.
