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.
