B Correct answer
Explanation

Stainless steel primarily contains iron, chromium (which provides corrosion resistance - at least 10.5%), and often nickel for additional properties. Tungsten is not a standard component of stainless steel - it's used in tool steels and high-speed steels for hardness, heat resistance, and wear resistance, but not in corrosion-resistant stainless steels.
