1. Copper
2. Titanium
3. Carbon steels
4. Stainless steel

Answer 1

Correct Answer - Option 4 : Stainless steel

Explanation:

Stainless steel:

• Steel (Carbon steel) is composed of Iron and carbon, which is the main component of stainless steel.
• Stainless steel differs from carbon steel by the amount of chromium present, which is added to make it resistant to rust.
• Stainless steel, also known as inox steel or inox is a steel alloy of iron, nickel, and a minimum of 10.5% chromium.
• Stainless steel is notable for its corrosion resistance, and it is widely used for food handling and cutlery among many other applications.

An alloy is a substance made by melting two or more elements together, at least one of the metal.
