What does a casket generally consist of in terms of its structure?

A casket typically consists of a body and a lid, which are fundamental to its structure. The body of the casket is the main compartment that holds the deceased, while the lid covers this compartment, providing closure and protection. This design not only serves a functional purpose but also plays an important role in the presentation of the deceased during visitations or services.

The incorrect options highlight additional elements or configurations not universally applicable. For example, the lid and a wheelbase option suggests mobility, which is not a standard attribute of a traditional casket. While some caskets may have a base or support mechanism for transportation, it is not a structural component like the body and lid are. The mention of handles in another choice refers to an accessory rather than a part of the essential structure. Similarly, while a shell and interior are important components in the overall design, these terms tend to refer to the exterior covering and lining of the casket rather than the basic structural elements. Thus, the focus on the body and lid aligns perfectly with the core definition of a casket.
