Which of the following is included in common stone products?

Granite and marble are recognized as common stone products due to their natural origins and widespread use in construction and design. These materials are derived from the Earth's geological processes and are prized for their durability, aesthetic appeal, and versatility. Granite, formed from crystallized magma, is often used for countertops, flooring, and decorative elements, while marble, which is metamorphosed limestone, is frequently employed in sculptures, tiles, and various architectural applications.

In contrast, the other choices consist of synthetic or manufactured materials. Melamine and laminate, for example, are types of synthetic surfaces typically used in furniture and cabinetry. Steel and aluminum are metals, widely utilized in construction and manufacturing but not classified as stone products. Similarly, vinyl and fiberglass are plastic materials often used in various applications like flooring and insulation, but they do not fall under the category of stone products either. Thus, granite and marble stand out as the definitive examples of common stone products.
