In what context is 'entombment' used?

Entombment refers specifically to the practice of interring a deceased body in a structure that is above ground, such as a mausoleum or tomb. This method is distinct from traditional burial, which involves placing the body in the ground. In an entombment scenario, the casket or body is placed in a crypt or niche within a mausoleum, allowing for above-ground memorialization.

The other options do not accurately describe entombment. Preserving the body for viewing relates to embalming or other preservation methods, while reducing the body to ashes pertains to cremation. Conducting a burial with a grave marker describes the traditional in-ground burial process, which is fundamentally different from entombment.
