Answer

Answer:

D. It is a durable metal and is commonly used for casting.

Brief Explanations:

Silver has higher electrical - conductivity than iron, so A is false. Steel (an iron - carbon alloy) is common, but not all iron alloys have a carbon base, so B is inaccurate. While iron is widely used, it's not highly valuable compared to precious metals, so C is wrong. Iron is durable and often used for casting, making D correct.
