Which of the following metals was the first to be used by men?

Copper

The correct answer is Option 1- Copper

Copper was the first metal to be used by men. It is a relatively soft metal that is easy to work with, and it can be found in nature in both its pure form and in ores.

People began using copper around 10,000 years ago. They used it to make tools, weapons, and jewelry. Copper was also used to make coins and other trade items.

Over time, people learned how to alloy copper with other metals, such as tin, to make bronze. Bronze is a harder and stronger metal than copper, and it was used to make a wider range of tools and weapons.

Copper and bronze were the most important metals for thousands of years. It was not until the Iron Age, which began around 1,200 BC, that iron became the most important metal.
