Which metal is ductile, malleable, an excellent conductor, reddish-brown, and corrosion resistant, used for pipes, wire, and cookware?

Explanation:
Copper fits this description. It is highly ductile and malleable, so it can be drawn into wires and formed into sheets. It is an excellent conductor of electricity and also conducts heat very well, which is why it’s used for wiring and cookware. Its reddish‑brown color is distinctive, and it resists corrosion well enough for plumbing and everyday use in pipes and pots. The other metals don’t match this exact combination of color, ductility, conductivity, and corrosion resistance, or they’re alloys with different properties.
