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.
