the answer is C ::::: The modern process of manufacturing steel begins with the extraction of iron from its ore (such as hematite) using a blast furnace. In this stage, iron oxide is reduced to molten iron by reacting with carbon monoxide (derived from coke). This molten product, known as pig iron, is the essential precursor that is subsequently refined into steel. While the second stage (steelmaking) involves oxidation to remove excess carbon, the overall foundational manufacturing process from raw ore is characterized by blast reduction.
