Which type of building is most likely to contain asbestos?

Residential buildings built in the 1980s are particularly significant in the context of asbestos presence because this time period falls within a range when asbestos was widely used in construction materials before its dangers became more widely recognized. While regulations and bans on asbestos were beginning to take shape, many homes constructed during this era still incorporated asbestos-containing materials, especially in insulation, flooring, roofing, and other building products.

The other choices are less likely to contain asbestos. New construction is generally subject to modern building codes and regulations that restrict the use of hazardous materials like asbestos. Commercial buildings built in the 2000s typically adhere to these updated regulations as well, significantly lowering the likelihood of asbestos use. Historical monuments, although they may have been constructed earlier when asbestos was more prevalent, can vary widely in their use of asbestos depending on the specific materials and construction practices of the time, making B the more definitive choice in terms of common asbestos presence.
