D Correct answer
Explanation

Brass is an alloy of copper and zinc. Bronze is primarily copper with tin. German silver (or nickel silver) contains copper, nickel, and zinc despite its name. Stainless steel is primarily iron (about 70-75%), chromium (12-30%), and nickel (0-20%) - it contains no copper, making it the correct answer.
