Which statement about pig iron is true?

Explanation:
Pig iron is the crude iron produced in a blast furnace. In the furnace, iron ore is reduced with coke and a flux (limestone) forms slag to remove impurities. The molten iron that is tapped off is pig iron, which carries a high carbon content and other impurities, so it is not pure iron. Flux isn’t converted into pig iron; it’s added to form slag and remove impurities. Since the blast furnace’s main output is this crude iron, the statement about pig iron being the final product of the blast furnace is true.
