What is the component part of the casket that serves as the lower section?

The base molding is the correct answer because it functions as the lower section of the casket. This component provides structural support and typically serves as a decorative element that connects the body of the casket to the bottom. In casket construction, the base molding plays a vital role in overall design and stability, ensuring that the casket maintains its shape and form.

The crown refers to the uppermost part of the casket, which is the lid or top, while the rim is the area that surrounds the opening of the casket at the top, often where the hinges are located. The ogee is a design element that creates a curved profile along the casket’s structure, usually found on the corners. Each of these elements contributes to the aesthetic and functional aspects of the casket but does not represent the lower section, which is why base molding is the most accurate choice.
