What is the name of the vehicle used by undertakers to transport mortuary paraphernalia?

The correct answer to the question is a hearse, which is the vehicle specifically designed for the transportation of the deceased as well as caskets and other funeral paraphernalia. A hearse is typically a large, elongated vehicle that can accommodate a casket and is often utilized during funeral processions.

An undertaker's buggy refers to a historical type of horse-drawn carriage used by undertakers before the advent of motor vehicles and is not commonly associated with modern funeral service practices. While a funeral coach can also be a term that describes vehicles used in funerals, it is usually synonymous with a hearse, making the hearse the more universally accepted term today. A casket cart serves a different purpose, as it is specifically designed to move caskets within a funeral home or to assist in handling during the service, rather than being a transport vehicle for journeys related to the funeral itself.
