Which item is used in high temperature areas?

• A. metallic
• B. Flat Head Screwdriver
• C. round pan truss
• D. Turnbuckle

Answer: (A)

In high-temperature areas you want materials that don’t soften, deform, or lose strength as heat rises. Metals fit this need because they have high melting points and maintain their mechanical properties at elevated temperatures. Saying an item is metallic signals a material choice known for heat resistance, which is why it’s the best fit for hot environments. The other options describe a tool or hardware rather than a material property, so they don’t indicate suitability for high-heat conditions in the same way.
