Which of the following metals was first used by man?

Correct option is D

The correct answer is: (D) Copper

Explanation:

• Copper was the first metal used by humans during the Neolithic Age (around 9000 BCE).
• It was used in its native (pure) form, as it is often found naturally in a metallic state, making it easier to identify and utilize.
• The period during which humans began using copper is called the Chalcolithic Age or Copper Age.
• Copper was primarily used for making tools, weapons, and ornaments.

Information booster:

• Gold: Gold was one of the earliest metals discovered, but it was primarily used for decorative and ceremonial purposes due to its malleability and lack of strength..

• Magnesium: Magnesium was not used in ancient times because it does not occur in a free metallic state and requires advanced extraction techniques, which were not available to early humans.

•  Silver: Silver was discovered after copper and gold. Like gold, it was mostly used for jewelry and ornaments due to its rarity and difficulty in extraction during ancient times.
