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 wrong. Steel (an iron - carbon alloy) is common, but iron alloys can have other bases too, so B is an over - generalization. While iron is widely used, it's not highly valuable in a precious - metal sense, so C is incorrect. Iron is durable and often used in casting, making D correct.
