Which statement correctly describes non-ferrous metals?

Which statement correctly describes non-ferrous metals?

• A. They contain iron
• B. They are highly magnetic
• C. They do not contain iron and have higher conductivity
• D. They are brittle

Answer: (C)

Non-ferrous metals are those that do not contain iron. Because they lack iron, they’re typically not magnetic and resist corrosion better than many iron alloys. A standout property is their electrical conductivity—metals like copper and aluminum conduct electricity very well, which is a common reason they’re used in wiring and electrical components. So describing non-ferrous metals as not containing iron and having high conductivity fits well with how they’re commonly used and how they differ from iron-containing metals.
