Which of the following is a common category of funeral service merchandise?

Caskets, urns, and burial vaults are indeed well-established categories of funeral service merchandise, as they are directly related to the final disposition of the deceased. These items are essential components of most funerals, serving both practical and memorial purposes. Caskets are used for body transportation and to provide a dignified resting place, while urns are designed for the storage of cremated remains. Burial vaults offer added protection for caskets, safeguarding against the elements and providing structural support.

In contrast, while vehicles, landscaping services, and commemorative clothing may be relevant in the broader context of funerals, they do not fall under the primary category of funeral service merchandise. Vehicles are generally considered part of the operational resources of a funeral home, landscaping services pertain to the maintenance of the burial site or memorial garden, and commemorative clothing, although it may be used by the family during services, is not a core item offered by funeral homes as part of their primary merchandise offerings. Thus, the focus on caskets, urns, and burial vaults clearly identifies them as central to funeral service practice.
