Question

which of the following is true of iron? a. it has the highest electrical conductivity of any metal. b. it can exist in many alloys, usually with a carbon base. c. it is highly valuable, has symbolic meaning, and widely used. d. it is a durable metal and is commonly used for casting. please select the best answer from the choices provided a b c d

Explanation:

Silver has higher electrical conductivity than iron (a false). Iron commonly forms alloys with carbon (e.g., steel), making b true. "Highly valuable" is not a main trait of iron (c false). While cast iron is used for casting, b is more universally true.

Answer:

B. It can exist in many alloys, usually with a carbon base.
