Which of the following is a common product that may contain asbestos?

The correct choice identifies floor tiles, insulation, and roofing materials as common products that may contain asbestos. Asbestos was widely used in these materials due to its fire-resistant properties and durability. For instance, many vinyl floor tiles manufactured before the 1980s sometimes included asbestos to reinforce their stability and heat resistance. Insulation products, particularly those used in older buildings, often contained asbestos for its insulating abilities and resistance to heat. Roofing materials, including shingles and flashing, also frequently incorporated asbestos to enhance their properties.

Other options like glass windows, plumbing pipes, and wood panels are not typically associated with asbestos content. Glass windows have not historically been manufactured with asbestos, while modern plumbing pipes are generally made from materials like PVC or copper that do not involve asbestos. Wood panels usually do not contain asbestos, as they are made from processed wood products, which do not require the heat-resisting qualities that asbestos provides.
