Option 3: Iron, chromium and nickel
Option 4: Iron and nickel
Correct Answer: Iron, chromium and nickel
Solution : The correct option is Iron, chromium and nickel.
An iron alloy with high corrosion and rust resistance is known as stainless steel. To get the desired qualities, it may also contain other elements, such as carbon; however, at least 10.5% of the composition must be chromium. Nickel is also typically present. Because chromium produces a passive coating that can shield the metal, stainless steel has a high corrosion resistance.
