The correct answer is D. All the above.<\/p>\n
Ferrous metals are metals that are primarily composed of iron. They are the most common type of metal used in the world, and they are used in a wide variety of applications, including construction, manufacturing, and transportation.<\/p>\n
Cast iron is a type of ferrous metal that is made by melting iron and then pouring it into a mold. It is a strong and durable metal, but it is also brittle and can easily break. Cast iron is often used to make pipes, valves, and other heavy-duty products.<\/p>\n
Wrought iron is a type of ferrous metal that is made by heating iron and then hammering it into shape. It is a strong and ductile metal, which means that it can be easily bent and shaped. Wrought iron is often used to make decorative items, such as gates and railings.<\/p>\n
Steel is a type of ferrous metal that is made by adding carbon to iron. Carbon makes steel stronger and harder than iron, and it also makes it more resistant to corrosion. Steel is the most widely used type of metal in the world, and it is used in a wide variety of applications, including construction, manufacturing, and transportation.<\/p>\n","protected":false},"excerpt":{"rendered":"
