Which of the following is NOT a common type of casket material?

The choice of paper as a casket material is not commonly used, primarily due to its lack of structural integrity and durability when compared to the other materials listed. Caskets made from wood (such as hardwood or softwood) and metal (like steel or bronze) are widely used because they provide the strength and longevity needed for traditional burial practices.

Fiberglass, while not as traditional as wood or metal, is used for creating lightweight caskets and is becoming more prevalent in some markets due to its versatility in design and resistance to environmental factors. In contrast, paper lacks the adequate quality and physical properties to serve as a reliable casket material, making it unsuitable for most funeral services.
