Explanation:

Magnets attract ferromagnetic materials like iron, cobalt, and nickel. Stainless steel often has a high chromium content and low magnetic permeability (depending on the type), so it may not be attracted. Iron (a), cobalt (b), and nickel (d) are ferromagnetic and attracted. Stainless steel (c) is less likely to be attracted.

Answer:

C. stainless steel
