Asbestos has been used commercially since which period?

• A. 1800s
• B. 1700s
• C. Early 1900s
• D. 1950s

Answer: (C)

Asbestos became a staple in modern manufacturing and construction during the early 20th century. This is when companies began mass-producing asbestos-containing products—insulation, fireproofing, cement and other building materials—so its commercial use spread widely. While there were earlier, Limited uses in past centuries, they did not represent the broad, ongoing commercial adoption that began in the early 1900s. The 1700s or 1800s refer to periods before this widespread commercial shift, and the 1950s come after that early adoption, when asbestos was already common in many products.
