Metals include which of the following?

Metals include which of the following?

• A. Water
• B. Wood
• C. Gold
• D. Coal

Answer: (C)

Metals are elements with characteristic properties like good electrical and thermal conductivity, malleability, and a shiny, metallic luster. Among the options, gold is the only one that is a metal—it’s a metallic element known for its ability to conduct electricity and heat and for being malleable and highly lustrous. Water is a compound made of hydrogen and oxygen, not an element or metal. Wood is an organic material from trees, not a metal. Coal is a carbon-rich rock-like substance formed from ancient plant material, not a metal. So gold is the correct choice because it is a metal, while the others are not.
