Correct Answer: Copper

Solution : The correct answer is copper.

Copper is a naturally occurring metal that may be found in either pure form (native copper) or as an ore. It is a soft metal, but it is also malleable and ductile, which means it can be readily moulded into various shapes. Humans initially utilised copper about 10,000 years ago. The Middle East and Anatolia have the earliest traces of copper usage. Axes, knives, and spears were among the many tools and weapons made from copper.
