D Correct answer
Explanation

Stainless steel is primarily an alloy of iron (Fe) and carbon (C), with chromium and nickel as key additional elements that provide corrosion resistance. The chromium content (typically 10.5% or more) creates a protective oxide layer, while nickel enhances strength and corrosion resistance. Aluminum, tin, copper, zinc, lead, and magnesium are not primary components of standard stainless steel.
