Question

What is a highly refined pure iron?

1) Cast iron
2) Wrought iron
3) Steel
4) Pig iron

Answer 1

Wrought iron is a highly refined pure iron. It is soft and easily worked but has little structural strength. Mild steel, which contains carbon, is stronger and harder than pure iron.

Step-by-step explanation:

A highly refined pure iron is known as wrought iron. Wrought iron is iron that has had all the carbon removed, resulting in high purity iron. It is quite soft and easily worked, but it has little structural strength. Mild steel, on the other hand, is iron containing up to about 0.25% of carbon and is stronger and harder than pure iron. Cast iron is a different type of iron that has higher amounts of carbon and is more brittle.
